I have spell check turned on in setting to check as I type. And yes I have two dictionaries downloaded and installed. But as I am working inside a program and I have to enter data into a text field, if I want it spell checked I have to right click and then click on Spell check for every field that I enter text into. For a while last week it was working without having to do that, and I had done nothing to make it happen. It was nice. Since then I realized I want spell check on. But I can't figure out how to set it so that it turns on for every field that I click into to enter text. Any ideas?

After Firefox update on my win 11 laptop, I had to reset my Firefox custom homepage and all my search settings and all my security settings. This should not happen. I did not lose my bookmarks or anything else.

Yesterday, I could log into my credit union account with Firefox on my Win10 desktop; today, after a Firefox update, I can't. I switched to Chrome, and logged right in. Called the credit union and was told it was the new Firefox update. Can I switch back to the prior Firefox version? Thanks!

I am building a game that uses the canvas. Since the last update a lot of images are not displaying. I have always used Firefox to test the game and never had a problem. Test on other browsers have no problem. I have tried on localhost and on a live server. I have fingerprinting turned off.

Upgraded to Firefox V.155.0 (64bit). Using Windows 11. The old version when accessing my Bookmarks allowed the option with a right mouse click to open that bookmark with the option "Open in New Tab". That option has disappeared. How do I get it back?

After updating from Firefox 154 to 155.0 on Windows 11, the download progress indicator on the Windows taskbar icon no longer appears at all.

What I see: - While a download is in progress, only the circular progress on the in-window Downloads button is visible. - There is no progress bar/fill on the Firefox taskbar icon, even when the window is focused and the Downloads panel is open. - In Firefox 154 this taskbar progress worked. - Chrome on the same PC still shows download progress on the taskbar correctly.

I checked about:config for anything related to taskbar/download progress and found nothing that controls this.

Is the Windows taskbar download progress still expected to work in Firefox 155, or was it removed/changed? Has anyone else noticed this?

Thanks.

Lost my original FF profile when I created a new 2nd profile. Opened FF. clicked profile icon. in drop down menu, I clicked on " create new profile". Set color, skipped most of the rest,then "set default browser to Firefox" using the button in FF dialog box, NOt Windows settings. Found and clicked on box " choose profile at startup". CLosed all instances of FF. Opened FF, box saying choose profile does not show my original profile, only the new one.

Help? I need to get back to my original profile, and keep the new one as choice at startup. How do I do this?

I had multiple tab groups which I had chosen to save and close. These tab groups have now completely disappeared and I cannot find them. When I began using Tab Groups, I had checked and there was no information stating that unopened tab groups would be deleted. I want these groups back. If I had known Tab Groups would disappear, I would have saved my tabs into a folder. The only Tab Groups that show up now are under "Recent tab groups". If tab groups are going to be deleted after a set period of time, it should be stated clearly in the tab group settings. It would also be really useful to archive them into a bookmarked folder so people don't unexpectedly lose hours of research.

There is seriously something wrong with the way Firefox operates. There is nothing wrong with the following site so why am I seeing this message?

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with news.sky.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

news.sky.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. Advanced What makes the site look dangerous?

The site is set up to allow only secure connections, but there’s a problem with the site’s certificate. It’s possible that a bad actor is trying to impersonate the site. Sites use certificates issued by a certificate authority to prove they’re really who they say they are. Firefox doesn’t trust this site because its certificate isn’t valid for news.sky.com. The certificate is only valid for: . What can you do about it?

For the last few days after an hour (or so) of use, browser windows try to load but don't finish. I checked the Mac activity monitor and see that FirefoxCP webextensions is hogging memory--8GB! MacOS 26.6.2, Firefox for mac 154.0.1. Did the same thing for MacOS26.5.2. Is AI doing in performance? How can I find what to turn off?
