I-Firefox Community Forum

Hey everyone, I recently switched to Firefox and have been running into an issue: when I scroll down with my mouse wheel, the browser sometimes jumps back a page as if I had pressed the side mouse button.

I’ve tested my mouse in other apps and browsers, and the issue doesn’t appear anywhere else, it only happens in Firefox, which is confusing. I’ve tried looking it up but haven’t found a solution.

Has anyone else experienced this or know what might be causing it?

Mouse is Logitech G502X Lightspeed

My usernames and passwords stopped autofilling even though they are still stored when I check in the Firefox Preferences. I've tried all the troubleshooting tips I saw in the forum like uninstalling and reinstalling the browser application on my Macbook Pro.

I'm stunned. I decided to try the "tab holder" feature that just appeared at the top of my sidebar with open tabs. I don't know why, but the tab holder went away, and with it the entire sidebar went blank. All my open tabs, my visual memory bank of places I frequent, just vanished.

I'm sick. Totally disabled by this.

Is there a place where newly added features are discussed, with instructions, etc.?

And how can I get my old sidebar list of tabs to come back?

I use vertical tabs and the new tab group feature which allows you to assign a group heading for 1 or more tabs. When I right click on a tab I can create a new tab group. Below this option is a button labeled "Closed Groups". If I want to use one of these and check it, the tab I want to assign to it is closed and the group name is not listed in the sidebar. It seems the "Closed Groups" can no longer be used. There is no way to get rid of them and I end up creating duplicates as new tab groups with the same names. I want to either delete the Closed Groups or be able to reuse them. Any solution for this problem?

I try to download a page, which has always worked. Now today its only partly being downloaded. All information on the page is not downloading. I have used the same link and downloaded on Chrome and it works just fine. I cant understand what i need to do to make it work as always?

Please help me out here, Axel

Is there a way using the userchrome.css file that I can get back the coloured toolbar icons I had for the home, reload, stop, backwards and forwards buttons? They were coloured until version 143 arrived. These updates just make Firefox more drab by altering things and preventing the settings in my css file from continuing to work! Anyone managed to fond any code for the css file that still works?

Watching CNN on Youtube suddenly freezes the tab. Randomly. Freezing means nothing can be done. The video simply stops without reloading or buffering. The mouse reacts, the pointer will activate ie highlight a button under the mouse, but when I click a button nothing happens. The tab freezes and nothing can be done. I can't even access the URL or search box. Nothing. I tried moving the tab itself or into another browser window, nothing. This tab is dead. Opening the same video in a new tab works like normal. I tried the usual things like deactivating Bitdefender, but no luck. Any ideas?

Just upgraded one computer to Firefox v143.0.1 and now familysearch.org is very slow and will not load hints. v142.0.1 is still on my other computer and familysearch.org works normally. Within familysearch, I can click on a hint and a pane opens on the right. It normally populates within a second or two at most. With v143.0.1, it takes a minute to partially populate, then it goes no further. With v142.0.1 it works normally. I've disabled add-ons. Cleared cache. Deleted TEMP files. Restarted browser. Restarted computer. Nothing has worked. Previous upgrades over the years have not had this issue. Other browsers (Chrome, Vivaldi, Brave, Edge, SeaMonkey) do not have this issue. Attaching a picture of this page: https://www.familysearch.org/en/tree/person/details/G4QP-T3S A free familysearch account is required to see it--only an e-mail address is required. The right pane has been trying to load for over 4 hours at this point. Normally takes about 2 seconds.

I have a number of old ReayNas Duo machines which I cannot afford to replace. Until recently they worked fine with Firefox after setting TLS to 1. Now, although I can log in, the menus done' work. Instead of taking you to the menu item the they close the menu & add 'Duo' to the page title. This is repeated each time you try to use a menu. The only exception is the 'logs' option, which seems to operate correctly. I'm using Firefox 143,0,1 on Linux Mint 22.2.

Hello, I'm running MacOS Sequoia 15.5 on a Mac Studio with Firefox version 143.0.1. Ever since I installed Adobe Creative Cloud, Firefox has been hanging on startup. The way I've found to temporarily resolve it is by closing the Creative Cloud software and manually killing the Creative Cloud Helper process, but I would rather not have to do this every time I start my computer. When Firefox is hanging, the 3 processes that use the most CPU are "fontd", "Firefox", and "Creative Cloud Helper". I would assume it's something to do with fonts, but I have no idea how to fix it.

Before Firefox added Tabs, I added the Simple Tab Groups extension. How do I move the contents of my many STG tabs into Firefox tabs? Also, there are different colored boxes on my top bar, with my STG tabs, and hovering yields "Unnamed Group Expanded/Collapsed." are these FF tabs?

I'm using version 143.0.1 (aarch64) on macos 15.6.1 (24G90). Ever since I updated to 143, many web sites no longer work.

For example, I get a completely blank page at https://banking.dkb.de/ - see source below.

At https://outlook.office.com/mail/inbox I get an error page - see below.

Here is another example of a blank page: https://www.aircanada.com/home/de/de/aco/flights.

Moreover, the inspector is completely blank for _all_ pages.

The abve pages work fine in Safari. I have used FF for ever since the first release, but am considering ditching it now. I can't find anything about this problem googling.

Please help!!!
