My switch from the release version to ESR seemed to go well, but my history and many of my settings and data, including my pinned tabs and extensive notes used by add-ons, were gone. I managed to reconstruct most of them, but was distressed to find that when Fx updated my ESR version those settings were again gone.

I have again restored most of the lost settings (including the one not to automatically update!) but I know I can't defer Fx updates indefinitely, and I also expect I may want to return at some point to the release version--and I desperately don't want to have to reconstruct my settings any more (or at least more than one last time). I'm not concerned about the loss of my history

Since I'm prepared to note all my settings first, starting fresh seems like a viable solution. I just need to know how (unless you can suggest a better option). I'd be happy with either the release or ESR channel.

Dear Sir, I have problems browsing some specific sites like presstv.ir Last Linux update helped to remove this issue but recent Firefox update brought back the issue. I have therefore avoid latest Firefox update on my other computers but still want to highlight the issue. I also wonder if this has anything to do with the restrictions US government has put on such sites belonging to the government of Iran?

I haven't been able to update Firefox (Mac, desktop) since version 82 because all updates use a font I can't read. Websites are displayed correctly, but bookmarks, most Firefox preferences (including about:config), tab headings and search imputs are as shown in the screenshots.

Today I downloaded version 90 and it's still happening. Please see the screenshots of the Firefox welcome screen, and the font selections in the preferences. The version for the screenshots is a new, clean download using default settings, with no addons or bookmarks.

I don't know if the font is a real language or not.

Last time Firefox updated, I managed to find information online about moving the website tabs so they were below the bookmarks instead of at the top of the screen. It was a huge pain-in-the-butt to do.

After a recent re-install, the tabs have moved themselves back to the top of the screen and nothing I do seems to be able to move them back below the bookmarks.

Is there a way I can move the tabs that doesn't involve spending hours hunting through posts on the web, changing hidden Firefox settings, and recoding .css files?

If not, why do you not give the option to move the tabs wherever the user wants? Especially when it makes far more sense to have the website tabs directly above the website being viewed, at least in my opinion?

I'm currently using Firefox 85.0.2 (64-bit).

Does anyone know any way to force Firefux [Ver 89.0.2 64bit] to stop the repetitious and constantly annoying pop-up that flashes on open, restart, or randomly appears, reminding me to once again update the apparently flawed software. I just updated yesterday!!!! Can I not trust that the programmers know what they're doing and that the system can actually work as expected without the intrusive proof that they screwed up again?! This is the worst business decision to make these things interfere with my workload. Every firefuxn day there's a new update alert!!! It makes me not trust this browser...

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 saw this answer https://support.mozilla.org/en-US/questions/1303747 but I don't understand anything from it, English is not my first language. Will I lose my bookmarks and extensions? Do I delete the folders in program files or run the uninstaller? When running the installer there is an option to "restore default settings, remove extensions etc", should it be on or off?

I deleted the folder, ran the installer again and set the option to restore default settings off, and still can't open firefox. Can someone explain in simple terms?

Hello, We run a website that uses a bookmarklet button which allows us to capture the current URL location and save it. This is placed on the Tool Bar where its easy for a user to use. Until now, its been working perfectly but with this latest update to FireFox we are seeing the pop-up blocking being activated with the yellow message bar at the top. Now this would be ok if we only had to allow the pop up once (by clicking allow site), but unfortunately the bookmarket button has to be able to work on all sites, which is the whole point of the button. So its impractical to keep allowing it every time its used. Disabling the pop-up blocker completely then works, but then the browser is open to other pop-ups. Is there any way to allow bookmarklets to display a pop up and not display a pop-up message? Without having to disable the entire pop-up functionality. Can the FF developers allow for user placed bookmarklets to not be pop-up blocked. Maybe an exception added for that. They are placed manually by the user so are allowed by the user only.

Thanks for reading. Paul.
