Firefox Support Forum

I had 3 windows with lots of tabs open and firefox only restored half of them. It's taking me a lot of time to go through history and finding the ones I lost and restoring them. I closed all firefox windows on exiting, verifying for each one to close the tabs, and yet this still happened when I restarted. I noticed afterwards that under options, under general, restore session was unclicked?? I have no recollection of doing that or any reason I would. I also saw that the sub box to warn me when closing tabs was also unclicked. Again, I would never unclick it and have no recollection or reason to have been fiddling with all that.

The only other thing is when first rebooting as I was going to history to restore sessions a Norton tab (I have Norton 360) popped up. I restored history and half of my stuff was gone. Does anyone have any idea of what's going on here?

When I try to get into my school's faculty website, I get this error (that just started today): "HTTP Error 400. The size of the request headers is too long." Is there a way to fix this?

This site https://app.wire.com/auth/ is not working properly after update to firefox 80. I see login screen, press arrow to login then server sync starts and stops after a second and I am back at login screen. Worked fine in firefox 79 this morning.

Hello, How does one clear remembered saved file locations. For example I saved a bunch of files to a directory called Nature. Later on I want to save some space images but when I click to save the image, it automatically goes to Nature. How do I clear it so it will ask me where to save the files to?

Thank you!

Every time I start up my PC I can find a firefox.exe process in the task manager that uses 40-50% of CPU and I have to terminate the process manually every time. Firefox is not enabled in my startup so I don't know what causes that process to show up and use that much of my CPU (note: an opened firefox browser with multiple tabs only uses around 5% of CPU just for reference)

Hi, can anyone help me out with two questions? 1. When I exit Firefox, a message always comes up saying that Firefox has crashed when all I've done is quit. 2. If I have Firefox open for more than a few hours, it won't let me save open tabs to my library until I quit and restart. Thanks for any advice.

Hi! This may sound silly, but I don't know if the programs need each other to operate correctly, like a build-on situation.

I was uninstalling programs today and see that I have, Mozilla Firefox 71, Mozilla Firefox 78.0.2, and Mozilla Firefox 80.0.1.

I'm good to uninstall the 71 and 78 right? Not sure why Mozilla didn't do it automatically when it updated; which adds to my hesitation to do it without asking.

Thanks!

I've recently noticed that Google is intercepting my old bookmarks and displays some stupid screen trying to get to do something. I don't ever use Google search but I do have Google Translate as a plugin on Firefox. What's the problem here?

Well, that's the issue. I returned to Firefox, but discovered the issue. When I try to upload a file as attachment to a message in Gmail, it gets stuck at the zero position. Other browsers (namely, Chrome and Brave) do it with no problem.

After I updated Firefox to 80.0.1 (64-bit) on my Win. 8.1 laptop, I can no longer access my ATT Yahoo Mail contacts list. The list is empty. The same thing happened on my Win. 10 desktop machine. My old Win. 7 machine, running the previous version of Firefox, is working fine. I can also access my ATT Yahoo Mail contacts on my cell phone Firefox app as well as my tablet. Please help.

After a recent FireFox update, I am now having a problem downloading Outlook.com webmail attachments. The download process appears to initiate, but when asked via popup "What should FireFox do with this file", the "OK" button remains 'grayed out' regardless as to whether the "Open . . " or "Save . . " option is selected. BTW: Using FF v79.0 w/ Win 8.1 and not having same issue using either Chrome or IE and issue does not appear to be file-type specific. Assistance would be MUCH appreciated as FF is my preferred browser.

Hi I would like to move mozilla to another hard drive. Reason: After startup my disk works at 100% and it takes some time to start up Firefox which I pretty much always want to do first.

I would really like to save everything as it is.

Ever since the latest update, FF is super slow, with more than 5-8tabs open it will force my disk to run at 100%, rendering my system which isn't crap useless. 3ghz CPU, 8GB RAM, Nvidia 4GB GPU, never had a problem before this FF 80 update...

Don't want to remove my extensions -Https everywhere, disconnect, Facebook container, WebRTC, Adblock ultimate, Ghostery, cookie auto delete and Magic actions....Otherwise nothing else running...no junk!

I use a good VPN only to connect to the net, and again never had an problems before this update...no other updates have taken place on my system for a month or way more!

I refuse to use Google, and am at a loss as I love Mozilla.....Web pages are also crashing and saying no server now, yet I check my net speed and it's rapid as always?!

Much love and thanks for all the help in advance.

If Enhanced Tracking Protection is on when accessing email on att.yahoo.com, I cannot open my contacts list. If I turn off protection the contacts list will display.

MSN does not work correctly.The slide show does not show the arrows that enable one to move back and forward. This has been going on for a few updates now. Also the refresh/stop button does not always work. I have to use Opera to get onto email and to read any news/articles on MSN.
