I needed to remove and replace my Firefox browser. In the original browser, I had a list of items on top of the browser with several things including "Bookmarks" which I could access. Now that I have reinstalled Firefox, that listing is no longer there. If I am making sense, can you tell me how to get them back on top? Cy

Hi there,

I'm experiencing a theming issue when using Firefox (flatpak) on Hyprland with a pure black (#000000) theme applied via a theme extension. When the Firefox window is out of focus, everything looks fine — the background is truly black as expected. However, when the focus is on the window, the blacks turn washed out grey, losing the #000000 appearance. This doesn't seem to happen in other apps and I don't seem to have any filter for the focused windows (except for borders), so it seems related to how focused windows are handled in Hyprland or how Firefox draws its content under Wayland - have you heard about this issue and could you help me diagnose it + find a solution? Is there a setting I could tweak either in Hyprland, Firefox, or GTK/Qt config to prevent this color shift on focus? Thanks in advance!

My Firefox keeps going down in my lower bar,it doesn't shut down or turn off it just keeps disappearing down in my lower bar and i have to click on it again to open the window back up on my desktop,it happens alot like several times while i'm doing anything and makes it difficult to do anything,like when i'm filling out applications my firefox browser just leaves my desktop and goes down into my lower bar and i have to click on it to bring it back to my desktop,i don't loose anything like when i'm filling out applications thank god,this has never happened to me before for all the years i've been using firefox,it doesn't happen at all when i open up my Microsoft Edge,how can i fix this without having to get rid of the browser and downloading it again and possibly losing all my bookmarks? Thanks for any input to hopefully resolve this issue. Bill

a couple of months ago FF suddenly stopped reopening the last session and instead opens always the same from a specific date. performance has been poor to the point that I can barely browse FB anymore. cleaning temp files didn't help. what's the best way to go about it? is there a way to export the history before doing a refresh or new profile? thanks

I'm using Mac OS 11.7.10. Firefox desktop no longer allows me to browse the internet. It just keeps spinning wheels. I've downloaded the newest version and it still crashes. What can I do?

Unfortunately, because of regular issues with a web site, I was forced to use FireFox as my main web browser. I say "unfortunately", because FireFox takes FOREVER to load, especially compared to Safari. But, more importantly, there was something about Safari that I really liked; that I apparently cannot get with FireFox. But this is odd, since FireFox seems to have so many more user preferences than Safari! And yet there appears to be no way to open FireFox in fullscreen.

If Safari is in full screen, when browser is closed, Safari remembers this, the next time Safari is opened in full screen. With firefox, I always have to go through long start up, and then I have to manually click zoom button, to go full screen.

Is this something you never considered or something FireFox cannot do? Again, I guess I am surprised at how many preferences are available for FireFox, but nothing like this, even though this is a feature in a competing browser!

I am not sure, but, even if this is more of a Mac feature than a Safari feature, since I am using Mac version of FireFox, seems like FireFox could or should work the same way as Safari! But, if not, why not??

Lately (for several weeks) I have been having trouble printing web pages with bold headings (Not Headers... Headings) in their pages. For example - recipes. The bold text which is usually also a larger font, is either missing completely, or just a series of dots.

It looks just fine in the print preview (I am on a mac, running High Sierra 10.13.6) and the problem exists whether I use the webpage print dialog or my operating system dialog.

I have tried both of my available printers and it happens on both printers, so it isn't a problem with my printers (I thought it might just be my old HP P1505)

I have also tried saving the page as a pdf through my print system dialog - the text problem exists there as well. If I use Safari (I prefer Firefox, but if this is going to continue, then I'll have to go back) everything is fine. (see the attached image - Firefox on the left, Safari on the right)

So there seems to be something in Firefox that has recently stopped allowing these fonts to make their way through from the screen into the print system.

new Date(1743623960000).toLocaleString(['en-ES'])

outputs "4/2/2025, 7:59:20 PM" in normal firefox and "2/4/2025, 7:59:20 PM" in Firefox Developer. Test on MacOS and Ubuntu.

My bookmarks have been removed from the bookmarks toolbar. I'm not sure how this happened or how to restore them. In the attached screenshot, you can see the bookmarks and their folders still exist under "Bookmarks Toolbar", yet they're gone from the toolbar itself. I'm not sure what to do next?
