Hi all, I'm having an odd problem. For some time now, whenever I look at a list of programs on my computer, Firefox shows up twice. In the last week or so, a new problem has cropped up. When I click on a link in Thunderbird, Firefox opens, but it's like I'm in a totally new instance of Firefox. My browsing history doesn't exist, it will not remember that I have already told Firefox to always open Zoom when I click on a Zoom link, and if I'm streaming a radio station, that tab will be in a separate window rather than in a new tab as it was before. What's going on here?

For some reason my Firefox has started to become much slower when I view / watch anything in full screen, it doesn't matter from where. A Twitch stream in full screen? The Video Player becomes slow, even using the escape key to leave fullscreen takes a bit. Youtube video in fullscreen? Same thing happens. No matter what site is being used, if I go full screen on any video player, everything becomes suuuper laggy. I've tested other browsers and they don't seem to have that issue so it's not a hardware or connection issue.

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

When pasting an image from the clipboard in Outlook Web Access in Edge there's right mouse button option to "Paste as Image". This places the image inline. In Firefox there's no option like this.

Safe mode (troubleshooting mode) doesn't fix this. Ctrl + V or Shift + Ctrl + V doesn't fix it. Shift RMB to get Firefox menu does show Paste and Paste without formatting but it doesn't paste any inline image.

I've attached a screenshot of Edge and Firefox with the Outlook context menu and Firefox context menu.

Firefox version: 140.0.4 (64-bit) Edge version: 138.0.3351.83 (Official build) (64-bit)

Hello everyone I just updated my operating system to refresh Win 11 and downloaded a fresh copy of Firefox signed in The problem I am having is when I switch to a theme it does not stay or show in the tabs Has anyone found a solution?

I had my startup page EXACTLY as I wished with two rows of most often used links to websites. While trying to find a solution to "page jumping" I use Help; "troubleshooting mode" and selected "Restart Firefox in Troubleshooting Mode". It did not solve the page jumping issue but did remove MY customized startup page and I do not how to get it back. I also used "Exit" and restarted Firefox but Firefox set my page to the default start page.

How do I get back to MY old startup page?

This is but one frustrating experience setting up MY computer to perform as I wish ... the computer culture has become "user unfriendly" .... what was once simple is now "too highly geek-ed".

Thanks in advance for your effort in solving yet another Firefox rabbit-hole problem.

You seriously need to remove the AUTOMATIC tab grouping, it's annoying as hell!

I know there's a workaround, but that's beside the point. You don't break into someones home in order to re-organize it, that's just bad practice all around.

After the latest Firefox update, I could run YouTube without problems for several weeks. Now YouTube will not run. How do I fix this issue? I suspect it is due to an adblocker but not sure!!

Over the past 2-3 months, Outlook, when opened on Firefox, continuously signs me out and forces me to sign in whenever I leave it open for more than a few minutes. Some days this occurs 5 or 6 times and has become very annoying. Even when I choose 'trust this device', or 'keep me signed in', or 'don't ask again for 30 days', it just automatically signs me out. I use 1 desktop and 1 laptop and this problem exists on both.

Also: I have a default font chosen for email composition that the system all of a sudden seemed to not recognize. I can select all content in an email and change it to my default font but it doesn't use it automatically. It either uses Segoe or Calibri depending on which computer I'm using. I have one laptop & 1 desktop. Oddly, if I place my curser down at my signature, which is formatted with my preferred font, the system will then use the correct font. As I'm typing, if I need to correct something, after doing so and trying to type the next word, it refuses to put a space between the where the curser is and the first letter of the next word. I literally have to start a new line by using the enter/return key, type the next word, then use backspace to take it back up to the previous line where it belongs. These are both small details but drive me batty!

I checked with my IT dept and they had me do a test drive on Chrome, which I NEVER use. Sadly, none of these issues exist in that browser, so for the time being I'm forced to use Chrome if I want to avoid the constant need to sign in and the other irritating malfunctions.

Anything you can point to or settings I can change to fix these issues?? Appreciate your assistance! Kayla Bates
