Firefox keeps crashing randomly, sometimes at startup, and sometimes just in the middle of a session. Sometimes just one tab will crash, and other times it'll be the entire browser. I ran it in troubleshoot mode and it still crashed, so it's not caused by an extension or anything. It never used to do this before and I don't understand what's causing this issue.

I used to have Firefox update itself using automatic updates, and occasionally I would manually trigger an update by checking the HELP>ABOUT menu. For some time now, I am getting an error message inside the ABOUT pop-up window. The current message is "Unable to check for updates due to internal error".

I've un-installed and re-installed several times. It doesn't happen on other computers I own where updates work just fine.

I tried searching, but couldn't find anything relevant

Any ideas how to fix this?

Thanks !

Until recently my browser accessed all the sites I have used for years and now I cannot access them. As an example the message I receive is "You don't have permission to access "http://booking.jetstar.com/au/en/booking/select-flights" on this server".

Reference #18.62052017.1660274157.1f6107dd Other sites like my banking site I can access freely on Edge but cannot on Firefox. No error message in that case, just says error try again. All this started after I loaded Norton. I have had them look at the system, and they have, but also point out that it is not them as I can access the site from Edge. I have looked at the help page and their are thousands of people with the same query but no fixes! As a long term supporter of Firefox I am disappointed that I now have to use Edge to do most of my business. HELP

Had a sign that I needed to update so I clicked update and it did not complete. I clicked Close Firefox and got XULRunner Error: Platform version '101.1' is not compatible with minVersion >=101.0 Max version <=101.0’ for ‘Firefox’ and can't,t get past it. I've updated for years and nothing like this has happened before. Do I need to uninstall and reinstall? if I do will I lose all my bookmarks and saved pages? Any other workarounds???

For a while now, several bank credit card sites are not working correctly when I use my Firefox browser. It did in the past and I didn't have any problems but lately I'm having these problems happening on sites I've used for years. If I use another browser it will work with no problem. In fact after talking with some of the support people at some of the sites that won't work, the suggest trying another browser which works fine. I'm talking like American Express' website which I use a lot. There are other sites other than credit cards that are not working correctly and again, their support agent will tell me to use another browser. I have tried different remedies like clearing cache, history, etc. I only use few addons like AdBlock which helps to cut down on trackers and information gathers. I have set my preferences to clear out my history and cookies. I have used Firefox for so many years without problems and with the same addons without any problems. So what is causing this to happen? I do enjoy using Firefox but if I have to keep changing over to another browser so sites will work, then maybe it's time for me to stop using Firefox.

Using Firefox, my page will involuntarily changes size or will highlight text not requested.

How do I keep Firefox from losing the internet connection just cause I don't want to close all the tabs I've had open the past week or so? I've tried clearing the cookies, and then reloading my open tabs, but it ends up losing the connection, just the browser itself. Other browser still works. Completely closing all tabs and restarting Firefox gets it working again, but dare I reload the previous session again, open all the tabs (acts like it's going to work), but then loses connection.

Hello, I'm teaching German as a foreign language - both f2f and online via Zoom. Up until recently I could call up the websites I would need for the online training, turn off the computer to save power and when I started it again the next day, all the tabs from the previous session would automatically reappear when I started Firefox. But now I cannot click the option "Open previous windows and tabs". I really don't want to completely delete this program and start from scrap because I'm scared I might lose all the bookmarks I collected for my job over the years. So could you please help me fix this problem without having to resort to drastic measures? Thank you so very much, kind regards, Silke Eckelmann

MY INBOX HAS CHANGED IN ITS APPEARANCE WHERE AS THE SIZE OF THE SPACE FOR THE EMAILS ALLOWS ONLY FOUR EMAILS TO BE VIEWED ON THE WHOLE SCREEN. I USED TO SEE MAYBE TEN. ALSO THE TOP OF THE SCREEN HES BECOME VERY LARGE WHICH CUTS DOWN ON THE AMOUNT OF INFORMATION I RECEIVE. I HOPE I MADE MYSELF CLEAR. THANK YOU RON

Hello. Whenever that blue broader on the new tab appears, it doesn't let me type on my keyboard and doesn't let me switch to a different tab and open my folder on the desktop whenever I press my keyboard. Does anyone know how to fix this problem?
