Firefox Support Forum

A month ago I started to have problem with twitch. After 5minutes or 2 hours- random times or random tabs, if I have opened more than 1, which is always the case. Some tabs or all, again it's random will give twitch 2000 error and refresh, closing tab,etc nothing will work, except closing WHOLE browser, not just tabs and this is not guaranteed that it will work.

I'm losing my mind with closing whole browser-windows-tabs on different monitors and then re-opening all of that again when I get 2000 error and I always do get it.

Did like 50 re-installs, it's always the same. I tried to go back to older version, but Firefox always want to create new profile saying I have old version installed and I DO NOT want that, I want everything as it is right customized,etc right now.

Recently I got a Mac computer and I installed Firefox in it. I can't find "About Firefox" in Application Menu.

How to show it in Application Menu like Windows and Linux?

Hello, I would like to know how to remove 'other bookmarks' folder from the right side of bookmark toolbar that showed up suddenly on my browser, it's right after the arrows to show more bookmarks. I can't seem to find a way to delete this.

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

My account is not syncing to any Firefox browser, extensions, passwords, bookmarks non of this attributes will be loaded to my browser back after re-installation, What might the issue be?

I am constantly frustrated by unresponsive pages / script warnings etc using Firefox. This never used to happen on previous builds -- I am using the latest 86.0 -- but these occur so often that I am about to say goodbye to Firefox. This does not happen when I am using Chrome and other browsers.

I have been through all of the suggested steps to deal with these unresponsive script/page issues, and none has worked.

Would appreciate any help on this, but as I say I am about to leave Firefox at this point for Chrome and other browsers.

Thanks in advance...

When I right click on an image in Firefox, I've always been able to select "view image info". This is very helpful, but now it appears to be gone in latest Developer edition. Do others see the same. If so, why was it removed? It's still there in the regular version of Firefox.

I use Firefox on 3 devices: - a PC at home (Win 10, FF standard instalation), - an Android phone (Xiaomi Mi 9T) - a PC at work (Win7) with the Firefox portable version.

I have the latest, stable, up-to-date versions of Firefox on all my devices.

The problem is when I save a bookmark on one of the computers at work or at home, and then the devices synchronize. Bookmarks between computers do not remember their position in the bookmark folders and are saved in the main folder.

I have already performed all the steps based on the instructions in this article, but the problem persists. ([https://support.mozilla.org/en-US/que.../1270667])

Firefox appears to have just updated. Now my bookmarks list is so long I have to scroll down to see everything. It looks like everything has been spaced out further, which I hate. It takes up was too much space. They were probably going for a more elegant, less cluttered look, but it just ended up making things more aggravating for me. There should be a way to adjust or turn off the spacing feature. Any suggestions?

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Currently on Firefox Developer Edition 89.0b2, clicking menu > Help > Submit Feedback, takes me here: https://mozilla.github.io/imo-placeholder/

It's a blank "Coming Soon" page with no information.

I'm experiencing usability problems with the new theme and I'd like to share what I'm experiencing.

HERE IS THE ANSWER Here is the answer to get TABS BELOW with Firefox V90 . . copy all of this code below the broken line into your - userChrome.css - file and save it. You can modify the 45px in this line if you wish to get an appropriate height . . just experiment with different numbers till you get it right --menubar-height: 45px; /*30px|41px=11px; caption buttons on menubar*/

Also to make the tabs wider or narrower, modify the line which is coded width: 50vw !important;

Finally you must enable - css - in Firefox, by typing about:config into your address bar, and search for toolkit. When all the toolkit options appear change the one which says toolkit.legacyUserProfileCustomizations.stylesheets to TRUE by click the icon in the right hand column. Than close Firefox and reopen, and check how it looks This will enable your - css - file to be read, and interpreted and accepted by the Firefox browser.

I am facing a strange issue where the Browser doesn't load the website for a minute and shows server error. However, this behavior is not specific to any website and the server error shows randomly. Sometimes the browser loads the website normally while other times it shows server error. Please check this screencast: https://jmp.sh/jEu4D9k to understand better. So, I initially tried to open calendly.com and it didn't load despite my multiple reload attempts. However, when I tried to reload it after a minute then it came to life.

I have been facing this issue for many months and I tried almost every solution I found on Mozilla community pages like Resetting Mozilla, Setting No Proxy, Turning Off IPv6, DNS Prefetching Changes, Turning On/Off hardware acceleration, Uninstalled Mozilla and Installed a fresh copy, Changed to Mozilla Developer Edition, etc. but no luck. Please note that the other browsers are working fine and don't have any issues.

Got an update to89.0 four days ago, that totally screwed up my userChrome.css file -- which I now fixed (Again, thank you to all that help with posting this updated file to get tabs on the bottom for us non-techies) but I am now getting notices to update to 90.0 Beta 5. This is new, as far as I know, and I certainly don't want to try Beta versions, if anything I'd like less updates to avoid the userChrome incidents ... Is there a way to get out of this Beta update cycle, and back to whatever "normal" update requests are? Thanks!

If I am on Youtube and click the logo icon in the top left, or the Twitter back button, or click on a recommended video, my entire computer freezes for 8-15 seconds. I can't close apps, speak on communication apps like Discord, nor can I even close the tab. I've tried troubleshoot mode, verifying browser file integrity, turning hardware acceleration off, and using older versions of Firefox and the issue seems to persist no matter what I do, I happen to really like this browser and I really want to try and find a solution for these issues. I am always running the latest version of Firefox (90b5) and use windows 8.1. When recording some of my performance data it seems the issue uses all the power my CPU (i-5 6600k) is able to offer. I don't know how to fix this and would really appreciate any help, thank you in advance.

Hey guys, just wondering if there's a toolbar workflow similar to Chrome and Edge where we can jump between profiles. I believe there is `about:profiles` though that requires a bookmark and a few additional clicks to jump between profiles.

Perhaps the profile icon on the toolbar can have an item that shows all available profiles?

How can I permanently force firefox's automatic updates to be turned off? Which guy modified the original design for the new version of Firefox bookmarks? Is there something wrong with that man's brain? Is the spacing of the new bookmark item too large to read? It's very uncomfortable.

I am using an offline web page as my default firefox home page and all was going well until I enabled sync. Now when I boot up firefox two things happen. It changes the address for my home page file to a folder NOT on this computer (the desk top) and won't retain the address I need for that folder.

I have just tried editing the bookmark for page. At the moment it seems to be working but I think sync is causing this issue and wonder if there is a fix for it?

Thank you.

My Firefox can't play any video on any websites. Youtube video keeps on buffering forever and I can't click on the play button. But preview images still shows up when I hover the mouse over video bar. This happened after I updated to latest FF version

I've tried every solutions provided by Mozilla Support: clear caches, disable extensions, uncheck hardware acceleration,.... you name it I've tried it all. Other browsers are just fine, but since FF is my main browser for work I don't want to switch to another one just for music or video.

Thank you for your support.
