I need to prevent my FF extension from closing when using a button with type="file".
In the past there were several workarounds and the last reported one was using the extension SDK but it has been discontinued since 2017 leaving only WebExtension API's as the only tool available to build extensions.
There was this previous post which is referenced basically everywhere but the extension SDK has since been discontinued as mentioned above.
There's also this thread on bugzilla but the latest activity was a couple months ago and prior to that 4 years ago.
Does anybody know a workaround?
Context:
Happens only on Firefox, Chrome works as it should
Extension I'm working on uses min version 57
Bug happens on desktop versions
Been developing on Windows, haven't tried any other OS's but this seems to happen on all of them
Steps to reproduce:
Setup a basic firefox extension
Add a button with type="file"
Click it to load a file and set any kind of code afterwards
The extension will open the file select (as it should) but will close the extension on the background so after confirming the selection the extension will be closed and any code that should run afterwards won't work.
Any ideas or workarounds known?
I installed selenium and used a python program to run chrome using selenium on my MacBook Air. Before there was an error on selenium, and after installing googlechrome drivers for selenium and creating a PATH using terminal, it opened a separate google chrome page that showed Chrome is being controlled by automated test software.
After around 30 minutes of running python and using selenium, I saved and closed out of everything.
In the next 2 minutes, I reopened Google Chrome to search something about web scraping, and the browser was the same one used by selenium. It still showed the Chrome is being controlled by automated test software notice, and there was a Chrome Automation Extension.
I tried:
logging in and syncing, but syncing was not available.
opening Google Chrome from application folder and dock, but nothing changed
deleting Google Chrome and reinstalling, but nothing changed
I don't know how to fix this. Can anyone help me?
Thanks in advance!
Ok, so I found out that the chromedriver was still running in the background. After I closed it using activity monitor, the problem was solved.
I am using Firefox 50.0. After auto update of Firefox to version 50.0, Firebug has stopped working and attempting to use it is showing an inbuilt Firefox console while inspecting any DOM element.
Is there any patch to use Firebug on Firefox 50.0 version?
Solve The problem by Changing Mozilla Browser Configuration Settings.
Open A Blank Tab
type about:config in address bar then press enter (click on I accept the risk!)
find browser.tabs.remote.autostart
select the option then click the mouse right side
Turn The Option As False
Close the browser for restart browser
open browser again, inspect the element. I hope It Works Properly.
I manage to get Firebug work again, so here is what I done.
Everyone knows that Firebug isn't being developed or maintained any longer because it can't work with e10s, so here is my workaround:
Download Firefox Developer edition so you can allow XPI installation.
firefox-53.0a2.en-US.win64.installer.exe or
firefox-53.0a2.en-US.win32.installer.exe
Run Firefox developer edition after installing and go to the about:config (type in url bar)
Find xpinstall.signatures.required (set to false)
Find browser.tabs.remote.autostart (set all to false: browser.tabs.remote.autostart.1 and browser.tabs.remote.autostart.2)
NOTE: The Multi-process architecture improves the browser's stability, performance and security by separating tasks into processes, you disabling it at own responsibility.
After that you need to restart the browser.
Now you can go at the Firebug repository and install desired version
Here you can find all Firebug installations
I chose latest firebug-2.0b8.xpi and it forking fine.
P.S. You can disable updates for Firefox Developer edition.
Hope it helps.
Head over to Firebug website, you can see following message:
The Firebug extension isn't being developed or maintained any longer. We invite you to use the Firefox built-in DevTools instead.
Also Sebastianz told me,
Firebug is discontinued. The team has split up, the former team leader Jan "Honza" Odvarko is working on the Firefox DevTools now.
As #Makyen said in his answer, Firebug does not work with multiprocess Firefox, so remove Firebug right now and try Firefox DevTools instead, it's not optional (sadly), unless you don't update Firefox :)
Update 1
Take a look # Why got Firebug removed after updating Firefox to version 50?
Update 2
Take a look # my answer here: how to revert firebug to old version
Firebug does not work with multiprocess Firefox
The Firebug site claims that:
Firebug 2.0.18 is compatible with Firefox 30 – 52
However, it also explains that [emphasis mine]:
Firebug 2.0.18 fixes issue 8030. The extension is marked as multi-process (e10s) compatible so, it isn’t blacklisted and users can continue installing it. This way Firebug can help users to easily migrate into built-in Firefox developer tools – in case it’s running in multi-process enabled browser. When opened in a multi-process Firefox, Firebug’s tools cannot be used. Firebug will then only assist the user with migration to Firefox’s built-in tools.
They also direct you to read: Unifying Firebug & Firefox DevTools
That page says that [emphasis mine]:
Firebug 2 doesn’t work in multi-process browsers (i.e. e10s) and converting it is too complex, so it will stop working when e10s is activated in Firefox. You will be able to disable e10s for a while to keep using Firebug 2, but this won’t last forever.
The fact that Firebug does not actually work in multiprocess Firefox will account for different people having different experiences with Firebug working or not working in a particular version of Firefox. Firefox automatically enabling multiprocess mode will depend on multiple factors, including what other add-ons are installed in the profile.
Using Firebug in newer versions of Firefox
Thus, to use Firebug in newer versions of Firefox, you will need to disable Firefox from entering multiprocess mode. This can be done from the about:preferences page (also available from Tools➞Options). This an option which is under the "General" tab as "Enable multi-process Firefox ...". If multiprocess is not available, this option will not be shown. This option can also be changed by adjusting the preference browser.tabs.remote.autostart from about:config. [Note: browser.tabs.remote.autostart.2 and browser.tabs.remote.autostart.1 also appear to be used to indicate default states, thus I suggest using the about:preferences page to change this option.]
You can determine if your Firefox is currently running in multiprocess mode by looking in about:support. The line "Multiprocess Windows" under "Application Basics" will state if multiprocess is enabled or disabled.
Set up profiles explicitly for testing
Personally, I have different profiles set up for each of multiprocess explicitly disabled and multiprocess explicitly enabled (set browser.tabs.remote.force-enable to true), so I can perform testing under both conditions, with the state of multiprocess being enabled/disabled being known in advance.
I had the same problem when I updated Firefox. I was so addicted to firebug but I moved on to Firefox developer edition - https://www.mozilla.org/en-US/firefox/developer/
It also comes with the firebug theme which resembles firebug UI and its efficient.Just install FDE and activate the firebug theme as shown in the image below :
I had the same unexpected surprise when ubuntu updated FFX and suddenly things like the script panel stopped working. Since I was in the middle of working on something with a short deadline, I was not going to have the luxury of learning the firefox developer toolset and desperately needed to get firebug working. The fix that finally worked for me was to set Firefox preferences not to update. Then download v 49.0.2
https://support.mozilla.org/en-US/kb/install-older-version-of-firefox
I also had to tell Ubuntu not to include firefox in it's upgrades.
It looks like firebug will no longer be maintained as a seperate project, so you will want to get familiar w/ the built in dev tools, but hopefully this buys you some time. Worth mentioning (if I'm reading this right, it sounds like it will be integrated into the native tools:
https://blog.getfirebug.com/2016/06/07/unifying-firebug-firefox-devtools/
https://github.com/firebug/firebug.next
Its working. You need to install one more add-on "Firepicker" and restart the Firefox.

I managed to resolve this issue by simply downgrading to mozilla old version using this url:
open https://ftp.mozilla.org/pub/firefox/releases/50.0/win64/en-US/
download and run the .exe setup
Go to Settings - > Add Ons
Click on extensions and search for firebug and firepath and then add those extensions
Hope this should resolve the issue. For those using Windows 32 machine can use the url
https://ftp.mozilla.org/pub/firefox/releases/50.0/win32/en-US/
http://toolsqa.com/selenium-webdriver/xpath-helper/
Open a new tab and navigate to any webpage. I have used www.DemoQA.com for demo.
Hit Ctrl-Shift-X (or Command-Shift-X on OS X), or click the XPath Helper button in the toolbar, to open the XPath Helper console.
Hold down Shift as you mouse over elements on the page. The query box will continuously update to show the XPath query for the element below the mouse pointer, and the results box will show the results for the current query.
If desired, edit the XPath query directly in the console. The results box will immediately reflect your changes.
Repeat step (2) to close the console.
I'm having troubles testing a StageVideo file locally. The HTML file that contains the swf loads perfectly in Chrome & FireFox, but when I go to open it in Internet Explorer 9 nothing happens (it just shows a white screen).
I've added the permissions for the location to the 'Global Security Settings' tab of the Flash settings manager (on the Macromedia website). I've also checked in the IE9 settings to make sure that it allows GPU rendering.
Has anyone encountered anything similar or have any suggestions as to why it might be blocked in IE9?
Thanks in advance.
My gut feeling is that you don't have the latest Flash Player for IE, but do have it for Chrome/FF since they're 2 different versions. The swf probably doesn't even load up because of the Flash Player requirement.
We are having some wierd behavior in firefox with silverlight. We have tried everything and I am hoping for some more ideas. Below is the behavior
Install firefox (3.6.12) and silverlight (4.0.50917.0). The versions there are locked and not controlled by us and on all our users machines.
Visit our silverlight application (also tried simple application with just a background)
Instead of seeing our application, you see "Get Microsoft Silverlight"
-- (about:plugins reports silverlight 4.0.50917.0 installed and enabled)
Visit site in IE, app works
Install or uninstall any plug-in (tried Firebug and IETab2)
After install, click "Restart" when prompted
After FF restarts, silverlight works as expected
Close firefox and reopen.
Once again, silverlight is broken
Any ideas? We tried the CWDIllegalInDllSearch entry in the registry to no avail. Please help!
I think it is a problem with Firefox that has been fixed with Version 3.6.14. See this BugReport on Bugzilla. A memory leak in prior versions, cause some problems in the Silverlight detection script of Firefox.
I can only suggest to update Firefox to version 3.6.14. But before i would try it in a local test environment to check if its really a bug in Firefox.
Update:
It seems to be a general problem with Firefox 3.6.x, cause some users report the same error as your with higher versions than 3.6.14. See here and here.
The only thing that springs to mind is disabling the plugin-container
In Firefox address bar type about:config
Read the warning, choose your preference to always remind you or not and accept
In the search bar of the config options now type: npctrl
You should then see the entry: dom.ipc.plugins.enabled.npctrl.dll
Change the value from true to false (simply double-clicking will change this for you)
Restart Firefox
EDIT
There is another workaround which is to disable then re-enable silverlight plugin. Rather than re-isntalling.
