Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

When I play a downloaded video that is in English, my downloaded file plays back in a foreign language, not English. What am I doing to cause this and how can I have the English version only in playback everytime? Thank you so much, being a pensioner I am eager awaiting the ability to donate to you excellent work as often as I like.

Hi. I have done a cleaning with CCleaner, so not sure if it affected firefox, but now the new tab page doesn't have my shortcuts any longer nor any buttons to add them. I had 4 rows of my most used ones. Now I only have the "recent activity" 2 rows....but they don't seem to fill in either...not sure what went wrong. in my settings the shortcut button is ticked. Is there a way I could revert to firefox that I had a couple of hours ago, to see my shortcuts back? I am not technical, so don't know what to do. thanks.

So I reformatted my hard drive and everytime I finish I reinstall Firefox. I have an account where I log in and it put me back where I left off with all my past bookmarks that I saved. Ive been doing this for 10 years but today not sure whats going on but when I logged if all my stuff has disappeared. Please help or contact Mozilla regarding this. I cant understand why one cant directly speak to the ones who developed this browser. Quite frustrating

Hi i accidentally adjusted the width of the sidebar too far and now i cant pull it back over. I have tried using the show sidebar button but nothing happens. is there a way to reset the width of the sidebar without having to drag it?

When I turn on my Mac and click the Firefox browser icon, it will not load. It hangs. I get a "not responding" message and have to "force quit," again and again until FINALLY it loads, after five or more failed attempts. This does not happen with Firefox on my laptop, only my Mac. Both Firefox and my Mac are up to date. Why is this happening? Please help. It happens every day when I try to load the browser. I am about to give up and move to Safari. Relatedly, anyone know if it's possible to export all my bookmarks from Firefox to Safari?

latest version of firefox sometimes will not ask to save passwords or remember them. seems if i try to set up a new password it doesn't want to save it, but set up pass key instead. thanks

Dear Community,

Since more than a month, when firefox was updated, all my bookmarks seem to be gone,which includes a lot of valuable research made over the past few years.

I have tried all suggestions that google give me to restore my bookmarks, but as far as I understand, there are no newer ones since 2019 (nor older ones than 2018) on my computer? That's what I find in a folder called 'bookmarkbackups' with json-files. Separately I also searched for 'json' and '.jsonlz4' and found nothing after 2019. Also I searched for .html, but nothing seemed to contain bookmark directly.

When I go to manage bookmarks > 'import/export' icon in the upper bar, it suggests two options, for 'nov 13 2025', or today's date), of which none provide me with any bookmarks.

Can I somehow still recover my research?

Do I really need to backup manually?

Or need I start saving all URLs in a word-document for my new research project?...

Firefox seems to update regularly, I currently have version 145.01. (I work on a Mac 2021, with Ventura 13.7.8)

I highly appreciate any advice on this matter.

Kind regards, Maria

if i search something on firefox the search bar doesnt show english and after clicking enter for the answer sometimes it doesnt come in english. i have chosen english as the only language but sometimes i get results in bangla too. i want my results to be in english only.

When I export a presentation from Perplexity in Firefox, the downloaded file is completely empty (slides without content).

If I do the same export in other browsers (for example, Chrome or Edge), the presentation exports correctly and the file is not empty.

So it seems this issue only happens in Firefox. Firefox 145.0.2

Had to recently reset my browser and lost all my history. Apparently it messed up my custom settings in some way as well.

New Tab still shows my FF homepage with shortcuts and history gone - I've managed to get those back but with one huge problem:

- Clicking on a shortcut opens it in the same tab, whereas earlier I had it working when clicking on a shortcut would open it IN A NEW TAB.

Where's the setting in about:config to fix this???

If this feature has been removed - why???

Recently, I've found that the OSX keyboard shortcut for focusing the next window in the current application ("Move Focus To Next Window" in System Settings) has changed its behavior. Pressing [cmd + `] will only cycle Firefox's windows until it reaches what seems to be the "end" of the current list of windows open. After this, I have to press [SHIFT+ cmd + `] to go backwards through the list of windows to re-focus any of the other windows.

Before, the behavior was such that I could just repeatedly press [cmd + `] and Firefox would infinitely cycle through all open windows, no shift key needed.

I haven't been able to reproduce this changed behavior in any other applications. Testing this in others (Finder, Safari, etc.) yields the cycling behavior instead of making me reverse the direction with shift to get back to the previous windows.

This is tied to the operating system's command. If I remap the keystroke to something else in system settings, I still need to use the shift key with it in Firefox once I reach the last open window.

Is there a way to get the old cycling behavior back? I find the key command with the shift key to be much less ergonomic.

I cannot complete an online payment from a checking account on firefox. I get to the point where it says submit payment and it always kicks me back to the same screen. I have to change browsers to complete the payment. Is there a setting that is preventing me from completing the payment?

I went away for a week, and during that time my iMac (apple desktop) turned off. When I rebooted it last night, Firefox loaded at the start as it has for years, but ALL of my bookmarks and activity history was gone. I've been collecting those bookmarks for nineteen years, and while there's a lot of useless stuff I've collected over the years, some of it is very important.

Please help.
