Hello, My Firefox recently updated (it's now v. 138.0.1), and now I can't seem to create tab groups anymore. When I move one tab on top of another, nothing happens. What can I do to get this useful tool back? Thank you!

I just set up a server with linux Ubuntu 24.04 Desktop, with Firefox 129.0.2 included to do some dev and testing work.

Problem: Firefox seems unable to see or open files that are above or outside the user's home dir tree.

The only extra packages installed are the LAMP stack and Google Chrome, which has no problem. (had to have something for A/B testing.)

I've tried entering the url of file:///var/www/index.html, I've tried selecting 'open with...' from the files app, etc. Nothing works.

I can get to the file through http://localserver/index.html with no issues. I've verified permissions on the entire directory tree to the file. Everything from end to end has read permissions for all, 755.

I've checked the following advanced settings: security.sandbox.content.level..............................0 (started at 4, now at 0, no effect or change.) security.fileuri.strict_origin_policy.........................false (default setting as installed.)

I am able to open file:/// and get a dir listing. BUT, if I click on var, it gives "Access to the file was denied." I even tried changing the permissions on /var to 777, but no change.

This seems to be a Firefox only problem, since Google Chrome works where firefox doesn't.

I've spent several hours searching for ways to fix this, all with no success. Does anyone have any idea how to fix this, or even what to look at???

Is there a way to block pop-ups on Meredith Dotdash websites, e,g. seriouseats.com, foodandwine.com, etc. Please see attachments

I frequently use a polish website that does not have an english translation built in. I want firefox to always automaticly translate that website to english or german. But i do not want to translate all polish websites. Just that one. How do i set that up?

I use Firefox desktop for buying and selling on eBay. Lately when trying to buy items on eBay I can not view pictures on some items. The other problem is the buy this item button does not work. Some times this also happens when on mobile. Firefox is up to date. I believe this is all part of pushing everyone to use chrome or edge by websites. First started using Seamonkey and now Firefox. I prefer not to use either one ) chrome, edge) browsers. Why would eBay want to limit people to buy products on eBay? Any suggestions to fix this problem?

When I click on a link on some websites, the link opens with no trouble. However some links don't open, just show the url. If I copy the url and paste it into a new tab, it then opens. How do I fix this? The links are from reputable sites.

I realize that the various stories that are presented are simply and excuse to provide more space for advertising but they are so very overloaded with superfluous, repetitious, word and story extending information that I am really sick of it. The stories are usually good but SO over stuffed that anymore I just go straight to the end of the story and skip all the stuff in the middle. I would not be surprised if many others are doing the same thing and thereby also avoiding the a lot of the many advertisements that are also stuffed into the story. So the story extending process seems to be defeating your purpose. I suggest that stories that are a little more to the point might be read more (and more ads read more) by people who don't have all day to wade through those terribly verbose stories. Roger DeWeese

You Tube will not go full screen. I've tried reinstalling, clearing cache, refreshing page, pressing F11. Nothing works. It will go full screen in a private browser, but not in a normal one.

Dear Mozilla Support,

I am experiencing an issue with Firefox when trying to log in to my company’s intranet (Bravida Sverige AB). The login process requires authentication via Microsoft Authenticator. However, every time I close and reopen Firefox, I am prompted to log in again.

According to the support team at my company, this behavior is not expected. When using Google Chrome, I remain logged in even after restarting the browser, but this is not the case with Firefox.

Could you please help me troubleshoot this issue? I suspect it might be related to session management or browser settings, but I’m unsure how to resolve it. I have re installed mozilla firefox.

Thank you in advance for your assistance!

Best regards, Björn

Suddenly, I cannot see the sidebar from several providers any more. What shitty update have you done this time ?? It must have been in the time between 19th and 21th November 2024 !!

The missing side bars very briefly appear (less than half a second) when the site is loading, however, then they disappear for no known reason !!

So what ???

Hi all,

Since recently Firefox keeps redirecting me as if I'm in Switzerland where I haven't been to ever since I use the internet. My location is in Croatia. I have tried to clear cache, cookies and browsing history multiple times, use incognito mode, my language is setup to English and I don't use VPN. Nothing helped. This unfortunately requires deeper dive because I can say for certainty that an individual who illegally surveils my device deliberately made this change and something needs to be done on Mozilla's end. Is there a way to directly contact Mozilla's support or what would you suggest to do to solve this issue?

Many thanks,

Lana
