I have set the setting for PDF files to Always Ask. When I select the "Open in Firefox" option from the dialog, it opens the PDF in a new tab in Firefox and ALSO launches Adobe Acrobat and opens there. I have not seen this bizarre behavior before today. How do I fix it?

Hyperlinks keep opening in new windows, not in the same/existing window where they were selected. Issue is not unique to Google Search results and occurring across multiple websites. At wits end trying to figure this one out. I have deselected the "Open links in tabs instead of new windows", turned off all extensions, and uninstalled & reinstalled Firefox. Issue is still occurring. Attached is image of my tab selections showing all turned off.

In the last 48 hours I haven't been able to access the following - https://www.co-operativebank.co.uk - they do not appear to be the problem - when I try the link the 'retrying' symbol on the top left of screen (?taskbar), flashes extremely rapidly and it appears the system can't find the website. Are you aware of this issue.

Hi, I'm running FF 149.0 (64-bit) on Windows 11. I've used profiles for a while now and on several occassions I've "lost profiles". Currently I have three profiles which I set up and edited the icon and colour associated with each. When I launch FF I see the Profile Manager and can select any of the three and I can create a new profile which shows here. However, once in any one of the FF profiles I don't see the others - by which I mean that when I go via the hamburger lines top right and click on the current profile, the 'other profiles' section is blank. I also cannot edit the profile from using the edit pencil top right (after clicking the hamburger lines and clicking on the current profile), it takes me to about:editprofile but the page is completely blank. Confusingly, if I go to about:profiles I see two profiles, neither of which shows up in the Profile Manager! I'm going round in circles trying to understand where to edit my exisitng profiles and make sense of the five profiles that don't all show up in the same place!

I use firefox password manager and have for years. I did not change my password in password manager but I can no longer edit or view my saved passwords. A box comes up asking me for my password but it keeps saying it is trying to allow me in to view my saved password but nothing happens. However, firefox still uses the saved passwords for all 37 of my saved sites and works to allow me to log into saved sites without hesitation. I tried changing my password to password manager and it tells me it changed the password but it will still not allow me to edit. When I click the edit button nothing happens. I have tried over and over and over. I often used my firefox password manager to go in and look up passwords to use on my ipad. I hope you can help. Thank you

Bully much? TyDraniu! Its people like you that makes the average user that has to result to anger replies leave because of the technical problems. I thank you for making my mind up for me, for more years than I can remember I used Firefox, even when it was giving me a hard time. I always returned because they seemed to really care. Now I am not so sure anymore. If you enjoy sarcasm all the more power to you. And just maybe someone that matters will take notice of this

Why are you trying to chase people away, after update i had to reinstall it cause nothing functioned right, now I have to jump through hoops just to install ad Guard. It should not be this difficult to use a website. I think I will move over to chrome where they actually try to make life easier and not more difficult

I have a problem with 'efficiency mode' in Windows 11. Windows 11 forcefully puts many of Firefox's tasks into efficiency mode marked by green leaves within task manager in processes tab. It doesn't seem to do this to anything else except Steam Client WebHelper. My Laptop is always in max performance mode in all possible settings as it is always plugged in (this does not influence efficiency mode). It slows down performance making things take longer to load and might even break them. If you try to enable efficiency mode on a task it even warns you of this: 'Efficiency mode will lower process priority and improve power efficiency but may cause instability for certain processes. Do you want to continue?' There is no way to permanently disable it. Currently out of 19 tasks 8 are in efficiency after I woke up my laptop from sleep (I have 5 tabs open). Only way to stop it is to manually disable each one by one (right click on each task and disable efficiency mode). But Windows 11 will turn them back on automatically usually within a few seconds (it seems to depend on opening new tabs, reloading them or waking up the PC from sleep mode). From looking it up online there seems to be a way to disable it in browser on Edge and Chrome but that might be something else (I do not use the so I'm not sure). There was a solution for Chrome but it doesn't work on Firefox.

Is there any way this can be disabled permanently through Firefox or Windows 11?

I find the new split view feature to be great, however I do find some basic keyboard shortcuts missing.

Things like: Focusing the other view Closing a view Splitting

Would be great to have these basic ones.

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

I have emptied cache, reset everything and I still get

This is from Cabelas.com but I am getting it more and more from other web sites. American Airlines, Delta.com, etc. I accessed the help and did all the steps about fingerprinting and turning off "enhanced tracking protection" and nothing helps. Any ideas? Don't like the idea of using Chrome or Edge, but Firefox is almost unusable for me now. If I have to keep using another browser for the sites, may as well just use that one only.
