Chrome based browsers display dark pdf correctly. Firefox does not. see attached images. all extension are disabled.

Why can't anyone fix this issue? Every day I have to go to about:config, enter "mica" then change from false to true or true to false to get these buttons to show up. It's ridiculous. I am currently using Firefox version 146.1 on Windows 11. Also, please note if I change the windows widget to true these buttons show up and are usable. The next days I have to change the windows widget to false and they show up and are usable so they work whether or not the widget is set to true or false. The problem is having to change the setting DAILY. I should not be having to do this.

Just updated my MacBook Air to Sequoia 15.7.3. Since that update, Foxfire will open, but when trying to open an article in Foxfire, Foxfire locks up and doesn't wan to shut down even with "force quit." What can I do?

I started using the new "Profiles" feature in firefox, and I created profiles one one device. However I am finding that the profiles are not syncing across my devices. Both are Windows 11 VMs, I tried doing manual syncs, singed out and back in to both devices. But the Profiles I create on each just do not seem to sync, is this the expected behavior ?

I am 82 years of age and did not grow up with the Internet. I have a total of only 8 hours of training on a PC. I have no idea how my PC got into 'safe mode' and now all of my extensions are disabled. I do not know how to exit 'safe mode' to allow the extensions to be enabled again. I tried following the instructions as provided, but to no avail.

Original Firefox account uses an older email now defunct and is no longer accessible. Security code being sent to add secondary email address can't be completed as older email account isn't accessible. Suggestions?

I typically use FF to log into social security accounts. I have not been able to use FF for a couple of months to log in to ONLY THAT SITE. I can on CHROME.

I've been extensively relying on the `Ctrl+Alt+X` shortcut to spin up the selected chatbot in the sidebar, but ever since I reset my pc (complete reset, cloud download of windows, clear all apps and files) and re-installed firefox, the keyboard shortcut isn't working for me anymore.

I installed firefox with chocolatey, upon noticing that the shortcut had stopped working, I tried to downgrade to v145, which didn't help either. So an uninstall and re-install later (this time manually downloading the installer exe), `Ctrl+Alt+X` still doesn't work. Although hovering over the chatbot's icon in the sidebar shows the shortcut in the tooltip.

More info: `choco uninstall firefox` created a backup of "Old Firefox Data" or something similar, could that have somehow persisted the malfunction across installs?

Any help would be appreciated! System: Windows 10 Pro Firefox: 146

In Firefox, I have several windows open, each with many tabs. (And BTW, I love the Firefox tab-organization feature.) I would like to empty the cache and delete all cookies. Will that close the open tabs? Is there a way to delete the cookies, empty the cache and preserve all windows & tabs?

      Thank you!

For some strange reason, I get this response when logging in to local newspaper on Firefox..image one. When loading the same newspaper on Edge, I see this instead...image two. I've been in contact with the newspaper but the techs there can't figure what's happening. Is there a setting I have wrong on Firefox? Thanks for your time.

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?
