I choose a new theme. After a while, I close Firefox. When I start Firefox again, my chosen theme appears briefly, then the default theme replaces it. Why? FYI: it doesn't happen with just one theme.

When opening a new website when a window is already opened I want Mozilla to add a tab and not create an entirely new window. How do I change this feature which presumably is in "settings".

Error raised,

There's also no way to add an exception? Just completely broken at the moment. I have to disable OCSP stapling to get it to work at all, which is less then ideal.

Currently using 125.0.3 (64-bit). I checked for newer versions of firefox and it's not saying anything. Chrome and Edge work fine. Encountered this on an android tablet with firefox, and went to desktop and hit the same thing.

I have used firefox for years as my browser with my home page set to google. I have always had a bookmarks toolbar but never a bookmarks side bar and do not want one. The other day a bookmarks side bar suddenly appeared. I have moved it from left side to right side and can delete it temporarily by using CTRL +B, but can't find a way to permanently remove it, i.e. make the default setting so that the side bar doesn't appear. can you help?

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

I'm encountering an issue with accessing my website, www.mobilepackages.in. When I try to access it using the HTTP protocol (http://), the website doesn't appear. However, when I use the HTTPS protocol (https://), the website shows up without any problems. What could be causing this discrepancy? Any insights or troubleshooting steps would be greatly appreciated!

This is almost surely a "security" or "privacy" design, but it's an error. In Firefox - only (this works fine in Chrome) - if I open the LastPass Firefox Extension, find a Site, and Copy the password, then go directly to an open AnyDesk remote access connection, and Paste (or, lightning bolt menu, Insert from Clipboard), what gets pasted is a single wrong character, NOT the password that IS in the clipboard. (If I paste instead into e.g. a local Notepad window, the actual password gets pasted). I asked AnyDesk support about this, and they confirmed that it's something that Firefox is doing. It shouldn't. Copy is copy. Paste is paste. Why would Firefox do something so that copied text (which just happens to be a password from a password vault extension) pastes wrong when the destination just happens to be a remote desktop client (AnyDesk) to send the password through to complete a login at the remote end? Anyway, how to turn off this wrong behaviour? thank you. (Windows 11 Pro, 64-bit, 23H2, Firefox current - 125.something today, but this has been going on for some weeks at least, AnyDesk version 8 current)

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

is there any Collections where category wise someone can save web sites ?

Presently, I do not find any. Hence, i am using Pocket and keeping there creating Lists, but it is not so cosy kind, Shall request Firefox team to create Collections in Firefox on windows 11

I have used Firefox for many, many years and have always loved it. Recently, it stopped loading some websites. I have read and tried everything I have read and still can't fix the problem. I have to switch to Edge to load the sites. I am tearing my hair out trying to get this fixed, but I will have to use other browsers if this doesn't get cleared up. Some sites load and most don't, but there is no rhyme nor reason to what it loads and what it doesn't. I do not have a great deal of tech know-how and cannot seem to fix this according to my research. I get no "error" messages except that the page can't load. Please help. I would hate to have to learn another browser.

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.

Firefox View Open Tabs is my favorite feature. I (used to) use it daily, but now, even though I have NUMEROUS windows (over 40) and multiple tabs in many of those windows, View Open Tabs is completely empty. I'd very much like to restore that 'index' without losing all those pages/tabs (it's my reading & ToDo list).

Sometime recently, I found it using gobs of CPU even though Javascript was (and still is) disabled, so I found the top CPU process and killed it. Instead of a single page going blank, Firefox crashed. Sometime after that I noticed that View Open Tabs was no longer populating. Maybe that contributed or instigated the dysfunction?

I get the message: Gmail may not work well with this browser version. Please upgrade to a supported browser. Just got it today. FireFox is version 125.0.3 for Windows 11. On gmail help, it said to disable extensions and add-ons. I did this, restarted Firefox and get the same message.
