i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

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???

Browsing works well on my Ubuntu/Linux 22.04.5 laptop except one site. Images are not loading. I can see it has js-errors which might be related. And that may be because some js files are being blocked. The site does work on my iphone though. And using Browserstack I can see it works with other OS.

The site is: knowledgecottonapparel . com

I've verified that others using Linux has the same issue, https://askubuntu.com/questions/1526728/issue-with-specific-site

YouTube keeps putting up the add block detection when I try to play a video. Apparently they can detect Add block Plus. Kubuntu 24.04 Firefox version 130.0 [64-bit] Mozilla Firefox Snap for Ubuntu Canonical-002-10. Add block Plus version sorry I can't find that information.
