Hi My normally excellent Firefox on Windows 10 has suddenly become unworkable,with the "Gah Tab Crash" message now coming up almost constantly. I have tried opening the browser in safe mode but to no avail. Any suggestions to travellinbilly@gmail.com. Fingers crossed.

Hello, I've been having trouble logging into some websites like Reddit and Instagram. I don't know why this happens but it keeps telling me that my password or my username is incorrect even though they aren't because they work on any other browser and my phone too. It's really frustrating because I have to switch browsers everytime this happens, is there any fix for this type of problem?

I've finally been able to get my Bookmarks Toolbar active and add what I wish to add but I cannot REMOVE a few of the sites on that toolbar. One is Your Getting Started and the other belongs to Dell. No matter what I do I cannot delete them or move them elsewhere. Can you help. Windows 11. I also need to know what happens to the overflow...do they continue on that line or do they go elsewhere. I don't use folders but have tried to move the sites I mentioned to no avail."

I've downloaded Firefox on a new computer. Following step #1, there is not green "download as" button so I can't proceed with the installation. Is a "donation" required before installation can be completed. If so, no problem. Kindly advise what I'm doing wrong.

How do I get rid of old email addresses showing in the dropdown prompt box when I'm signing on to a site? The old address/password combos have been deleted in my password manager, and I haven't figured out how to get rid of them at the login point.

About a week ago I started getting the never-ending spinning wheel of doom as Firefox tried to log me in to my account with The Guardian newspaper. My password and username have not changed in years. Can log on via iphone and iPad without a problem and also using thew same username/password combination on other desktop browsers so problem seems to be only with Firefox. Have done all the usual cache clearing etc. Would a recent upgrade have affected this?

How can I ensure my website is mobile-friendly when viewed in Firefox? I’ve been working on my site at Connect Career, and I want to make sure it looks great on mobile devices.

In the password manager I want to change the URL of the website from https://test.xxx/ to https://test.xxx/login/part1 . I first delete the old entry and then create a new entry with the new URL. The old address is then displayed in the password manager each time. How can I successfully change the address?
