Firefox Support Forum

The "about:addons" page will not load, more specifically the page layout loads however it is stuck at "Loading [moving wheel]". The other pages such as "Appearance" and "Plugins" will load, only the "Get Add-ons" tab will not. If I click "Check for Updates" (located in the [cog] drop down menu in top right) it instantly returns no updates available.

I have tried setting the theme to Default and loading Firefox in Safe Mode with addons disabled. This has not fixed the problem.

I have attempted to attach a screenshot however it is not uploading, here is a mirror: http://imgur.com/EkyFc1X Similarly, the troubleshooting plugin installed but did nothing; I used the manual copy text method however it appears to provide no usable information.

Since upgrading to the latest version I am trying to find replacements for the newly disabled add-ons. I first tried this on Friday the 8th. The same problem has been happening all weekend including today and I imagine since I installed this version. The exact wording is downloading and verifying add-on.

everytime I start up firefox It asks me to verify my addons. these are adblock plus, adblock plus pop-up , Ageless, clean links, google privacy, https-everywhere, and a us spelchecker dictionary. plowed trough the community answers and tried about everything: refresh, delete and reinstalled, one addon at the time see if there is a problem there, reset preferences,Prefs.js, User.js and Sessionstore.js,extensions.sqlite, extensions.ini, extensions.cache, extensions.rdf fix, firefox properties are correct no admin startup ect. so in short tried about any solution out there. any way to fix this, and would downloading firefox beta help (aurora)?

thanks

I can't update Firefox to the latest version. I HAVE to use version 52.9.0 because ANY later version will NOT open a link in a new tab when I right click mouse "open in new tab." NOTHING happens.

Help! All my language packages have been disabled while updating to Firefox 54.0: "Firefox was unable to find updates to your incompatible add-ons" and when I go to addons.mozilla.org, all language packages I need (including English! (GB)) show as "not available for Firefox 54.0". I'm a linguist so I really need them!! what shall I do? Do I have to go back to Firefox previous version?? Thanks for you help

Hello,

Suddenly, when using the screenshots tool, it doesn't save save my shot when I screenshot it and click on the "Download" button anymore.

Nothing happens and I can't see anymore that blue down arrow beside the URL bar.

I've always had an firefox extension from myendnoteweb.com in my toolbar, but now forefox have blocked it. Why? And is it possible to unblock it? Also I can't submit the add-on to AMO since I can't download the file from endnote.

I have a number of Add-ons, and the icons on some of them take up a lot of room. So the navigation bar is crammed full. I added the Add-on bar that shows up at the bottom of the screen. However, I haven't figured out how to get the Add-on icons moved to the bar at the bottom. I'm sure it's something very simple but I haven't found the magic combination to do that yet.

I would appreciate any help/suggestions you can give me. Thanks for your help.

I don't know if it's relevant but I'm using two Toshiba laptops running Windows 7 and the other is Windows 10. Both are 64-bit. And it's is Firefox 42.0.

When I open up Firefox an error/crash message shows up. How do I keep this from happening?

I've tried loading a screenshot of the error message but it won't complete. Sorry.

On some sites and a NextCloud installation, I suddenly cannot click on some links that report following error in the console: Uncaught Error: Permission denied to access property "apply"

   jQuery 7
   clear searchprovider.js:292
   attach merged-index.js:11661
   jQuery 8
   _setCurrentDir merged-index.js:5820
   changeDirectory merged-index.js:5752
   actionHandler merged-index.js:3432
   action merged-index.js:2894
   _onClickFile merged-index.js:4757
   Underscore 3
   jQuery 2

I've checked and disabled add-ons to see if these were blocking somehow, but no result. It worked fine before, so my suspicion is something changed in FF78? Thanks!

When using Twitch to watch videos a new tab will suddenly open to the address

Does Mozilla know this is happening or is this some kind of virus?

I have multiple add-ons. I am using their functionality but I would like to hide them so it only shows 2 of them, without losing the effect of the others. How do I do that?

Hi, I find this chrome video screenshot extension very useful: https://chrome.google.com/webstore/detail/video-screenshotter/ppkojackhibeogijphhfnamhemklmial . It allows me to screenshot a video from practically any website. But I am trying to get rid of chrome and stick to firefox. Is there any firefox addon similar to this? I've looked everywhere.

Mega.nz has an add-on that is verified and firefox does not want to install it because it is not verified!

What to do to get that Mega add-on?

I had a system crash, probably with Firefox opened.

After restarting PC and starting Firefox, most of the addons I have had lost all of their settings and were reset to default - Tampermonkey lost all the scripts I had installed, uBlock lost all settings and rules, etc. Weirdly some extensions kept portions of their settings, like TreeTabs saved tree structure despite also getting reset to default.

Additionally Firefox also got its own settings reset to default, while the tabs from my session and bookmarks were saved.

Is there any way to recover addon and Firefox settings, is there any backup of them?

using 61.0.1 (64-bit) Mozilla Firefox for Linux Mint, mint 1.0 Files saved with Save Page WE 12.1 When attempting to open an html file the result is "Gah. Your tab just crashed. We can help!

Choose Restore This Tab to reload the page."

Is this fault with FF or WE? Thank you, Doug

Worked fine, but now typically shows , e.g., "no media to process in current tab." Or it seems to download but then gives error message "MP2T No data received." It had just worked fine with Firefox 67.0. DownloadHelper v. 7.3.6. Looks fine in the Add-ons/"manage your extensions" tab.

Hi. I made a dumb mistake and installed an add-on or extension (not sure which) that I was hoping would allow me to view YouTube videos in full-screen. Unfortunately I can't recall the name of the add-on/extension.

The problem is, now every time I open Firefox it opens in "full screen" and NOTHING (including F11) will allow me to access the taskbar, the address bar, or any of the other Firefox controls. I can't do anything at all but view the home page in full-screen! The only option I have is to hit control-alt-delete and close Firefox.

I tried uninstalling and re-installing Firefox and this didn't solve the problem. Please help. Thank you!

P.S. I'm writing this in Internet Explorer since I currently can't use Firefox.

I've downloaded and installed Evernote Web Clipper 6.015. It shows in my list of add-ons but it is greyed out, like it's not active. But it also doesn't give me the option to activate it. Accordingly, it does not show in the toolbaar like the other add-ons, e.g. FireShot.
