I reset my PC and reinstalled Firefox last month, but my bookmarks were never recovered after I logged in my Firefox account. A couple of months ago I installed Firefox on another PC (to which I no longer have access) and it showed all the synced bookmarks, but this time it doesn't. What should I do? Thank you

I think I may have accidently pressed a button and made the homescreen giant even though it shows as being at 100%. Does anyone know of a way to return to to normal?

This is a very bizarre problem. Basically I can't install any Firefox addon neither on my desktop OR may laptop. I noticed this issue just couple of days ago. When I try to install any addon normally, from a link, it tells me that the addon can't be installed because the file is corrupt. Tried several addons, all same problem. On my desktop AND on my laptop. On my desktop I'm running ver. 103, but on my laptop I still had ver. 102.1, so there is no Firefox update issue. When I try to install addon from xpi file, it tells me that I have no permission to open that file and that's it. I tried to take ownership of that file but it didn't solve the issue I tried to disable my AV program, but it didn't do anything. On my laptop, I tried to refresh FF, no help. I tried to start FF in safe mode, same problem. I created new profile, same issue. Eventually, I totally uninstalled FF, removing program itself, removing Appdata folder and even registry entry. Installed fresh copy of FF, same problem exists. Then, I noticed one thing. When I tried to sync fresh FF installation on my laptop, it synced everything, EXCEPT for addons. So, something is preventing me doing anything regarding addons. Themes install just fine. I've struggling with this problem since yesterday and at this point I totally ran out of any fresh ideas how to solve this issue, thus posting here. I'll appreciate any fresh idea as what to do next. Thanks

When I go to my bank's login site, I get a message saying that I need a newer browser. I have the latest version of Firefox, and I used to be able to log in just fine, but I recently reset my browser and I seem to have lost some settings. I have tried adding an exception for this site's cookies in Settings, and I've also tried turning off enhanced tracker, but the site still doesn't work. Is there a way to tell what is broken and then fix it? Thank you.

When I go to websites there are unusual characters(light font) that are displayed. That shouldn't be there. How do I get rid of them?

See attached screenshot.

I'm running Firefox Dev edition and I cannot get it to load any pages except for Mozilla pages. I have tried all the fixes suggested there and it still refuses to connect. I'm at my wits end. Any hail mary optoins or do I have to reinstall and start again?

I just updated and now everything is larger. The bookmarks toolbar is larger, the tabs are larger... There's barely any room for the page I want to see. How do I go back to the previous version? OR how do I get stuff back to normal? Thank you for any help. It will be appreciated.

Duplicating of bookmarks now sorted by clearing all, thanks. Now, in the drop faves the bookmark menu is missing but appears in left pane when manage tab pressed? what is going on!

Firefox 103.0 - 64bit; Windows 10. Since Monday, I have been unable to download anything. The download starts and after a couple of seconds reports "Failed". I have tried starting in safe mode and it still fails. I've done a refresh to no effect. I also have another machine which has the same Firefox version and a copy of the profile but still runs Windows 7. No problem with that one....

Anyone got any ideas?

At some moment I´ve got a pretty big sessionstore file (6,6 Mb) which does not load properly. I´ve tried a few of FF versions and settings. My current version 103.0.1 64 bit loads it for few minutes and crashes when tabs appear. Some older versions loads it but after that have various problems with program interface: new tabs sometimes won´t open, no float tips when I´m hove cursor over tab header and so on. Also in such cases browser often crashes and not update old sessionstore file. I have 16 Gb of RAM, FF takes up to 5,5 Gb before tabs appear for moment and FF crashes. I have such big sessionstore file earlier (for example, 24.07.22 it has size of 6,5 Mb), but all worked fine. Maybe there are any internal setting that I have to try?

I set up sync before reinstalling Windows 10 on my PC, currently everything is still intact on my iPhone, but gone on the PC, because I reset my password?

How can I get everything back in Firefox on my PC?

Excuse me, I realize there must have been many similar posts.

It periodically blinks and that breaks buttons that open menus and closes context menus from Firefox. Also disables some keys, the tested list is arrows, might need to test that on all. As it's version-independent, it might be a dependency issue. It also happens in safe mode, which is saddening.

I've just updated my iMac which uses mac OS Monterrey12.5. As a direct result I can no longer use the Mozilla search window on the Foxfire Homepage. It's still there but it won't allow you to enter information into the box. Is there either a way to restore the functionality of the search window or at least disable it in settings so I don't have to see the window and be reminded that it no longer works? Thank you in advance for whatever assistance or answers you can provide.

I canNOT access outlook.com (using Mac Monterey) - it was working a couple days ago and now all I get is a blank screen. I can access it using Chrome so I'm thinking this is a Firefox browser issue. I'd REALLY like to continue using Firefox but need to access it on the same browser I've been using.

HELP!!

THANK YOU!

I woke up this morning and my tab bar on Firefox was out of control. I figured out how to shrink the tabs in about:config. However, there is a huge space at the end of the tabs that is completely unnecessary. I've been googling all morning. I tried to find compact mode--but "density" is gone, even when I go back into about:config and enable it. The only other help I found was to change the CSS code and unfortunately, that is outside my wheelhouse.

Is there ANY way I can get my old tab bar back so that the tabs fill the top of the screen as opposed to having a huge empty space at the end?

When printing double-sided from Firefox 103, the second page comes out upside-down. A previous thread 'Two-sided printing rotating on wrong axis' reported this problem for Firefox 85 / 86, and said that it was fixed by updating to the current version. I have the current version, but am getting the same problem. I have tried manually setting instructions to flip on long side (portrait orientation), but that doesn't work. Help!

Hi!

Firefox updated to 103.0 (64-bit) tonight and now zoom is at 110%. I have gone in and put it back to 100% but it's not changing. When I go back and look, it's right back to 110%.

How can I fix this?

Thank you!
