Firefox Support Forum

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

since the last update, the shortcut keys to highlight a word at a time left OR right are both highlighting the next word AND also jumping to the last tab. AGAIN! I noticed this was identified as a problem back around 2019 in a search. I now cannot move fluidly within text, nor highlight a word at a time quickly. Either it's whole line or simply a letter at a time... which results in a pretty incompetent, crippling experience. PLEASE FIX!!

Hello,

A couple of months ago I discovered that I no longer have the ability to edit, delete, or dismiss a shortcut from the home page of my desktop. I did read that the 3 dots will appear if I hover over a shortcut. I tried that several times on different shortcuts but the 3 dots never appeared. Is there another way to edit, delete, or dismiss a shortcut? Or even better is there a way to restore the 3 dots?

I cleared my cookies, cache, history and data like I was told to when I connected a new router so all of my shortcuts have changed. A few that are there now I don't want and I do want to add several new ones.

Thank you for your help!

Hello,

I cannot open the uwyo.edu website on my Firefox browser. I have no problems with other browsers. I tried and checked the solutions people shared, but none of them worked for me. I checked the DNS and different networks, and I also checked the link below:

I would appreciate it if you could help.

Thank you and best regards, Farshad

Have been unable to view readers comments for a number of weeks and can figure out how to fix. it is not all the time, like last night were available but not this morning. All other browsers there is no issue including DuckDuckGo. Am using Ublock Origin, but have been using for years with no issue, even when turn off result the same.

I've been using a Rewards site regularly (3/4 times per month) for several years without problem. This weekend the attached pop-up appeared. It makes no difference whether I select Resend or Cancel, the program just re-displays the pop-up trapping me in an endless loop. The only exit is to close the window and abort the process. I was able to complete the task without any problem using Edge instead so it appears to be a Firefox specific issue. I haven't consciously changed anything since last using the site successfully on 24 May. Any help/suggestions appreciated.

FireFox assumes that text size is the same for all pages in a domain, rferl.org for example. That is _not_ true. If I have set size to 50% and then take a link to a page that's different and have to set size to 67% to read it, when I return to the original page, size is 67% and text is too large.

I am not referring to anything regarding YouTube. This issue is with my Firefox web browser. When I long onto frequently used web pages parts of the page are no longer visible. What causes this and how do I fix this?

I have been working for Data Annotation for nearly a month and never got this error before. I need this money for rent! I'm trying really hard not to freak out here but today is the deadline for rent and the only way I'll get that money is to log on to this website so I need help and I need it now.

I have just upgraded the OS on Mac Mini with the M1 chip to Sonoma (14.5) I am running Firefox 126.0.

Now it seems that I have more than one problem since the upgrade. The browsing history in my sidebar is not current. It is running about a day behind.

I reported earlier that the type on my LinkedIn is only out 7 pt when my settings have the minimum size at 14 pt.

Somebody please help. I'm afraid to do a refresh because I don't know what it will do to my banking settings.

Hello! I installed Firefox about a year ago, and for the entire duration it seems about 60% of the time the default fonts on various websites look weird (bold?). I have tried uninstalling/reinstalling Firefox, clearing the cache, etc. See attached images for examples. Help!

Firefox is synced on all my computers. Same version. Same extensions. I can't login on my primary desktop as of last night 5/23/24. I can login/watch Prime on my laptop. My desktop gives me the attached error.

Since 2 weeks, I have been facing a UI error in the address bar. Whenever I select it to type something, the bar and search suggestions jump up off-screen. Pic attached.

Just checking, can I still make a $3 monthly Paypal donation to Mozilla, or is that amount too small, or does it expire, or something to that effect? Thanks much!

I've migrated to Firefox from Chrome and am getting everything as close as possible to my Chrome setup. This is a usability issue when I zoom on an image, that has a larger version. Chrome allows me to zoom to the full extent of the image, but Firefox screen shakes and doesn't allow the same detail. Screen recording and links below.

How to change the background we want on the Mozilla Firefox front screen, as I gave the picture

Tab detachment was working fine until updating to Firefox 126. Now the tabs cannot be moved, detached or dragged to another window.

In about:config, browser.tabs.allowTabDetach is set to true

Suggestions?

I recently came across a webpage that is made to look like a message from Firefox letting you know you need to update the browser. Where should this be reported? I'm sure this is some malicious download though I have no way of checking.
