Firefox Support Forum

Hi, I‘m not sure if I selected the right topic for my question but I can‘t find an answer to my query anywhere, so here goes:

When I opened Firefox on my Mac today (all up-to-date), a pop-up request by Firefox (cf. attached picture) showed up: "Firefox needs to download the font "Weibei SC". "Weibei SC" is 17,4 MB." with the options "Skip" and "Download".

Puzzled by this odd request, I wanted to skip it, but anytime I clicked skip the window would pop up again. I never clicked on download and I actually closed and reopened the browser, without having it show up again. I even restarted my device and reopened Firefox but it didn‘t show up again.

Now, I want ro believe that there is nothing to worry about, that it was a software blunder of some sort and that maybe normally it just installs fonts in the background without me knowing. But for the sake of my own peace of mind, I‘d feel more comfortable if someone who knows the software better than I do, explain to me what this was or might have been, and hopefully that it was nothing harmful.

Thank you!

MY Windows 11 laptop crashed and OS may need to be reinstalled. Will this wipe out my Firefox browser bookmarks. I would like to save the bookmarks somehow. How do I do this without access to that system?

greetings, I had trouble with firefox crashing, so i uninstalled it and reinstalled it and now I have lost all my passwords and bookmarks from the previous installation. I have tried to fix it, but I am completely computer illiterate. Please help. I am unable to do this with directions found in my search. I need someone to do it FOR me. Please help.

Since the latest update Firefox doesn't show up in the browser list. I don't want to uninstall to reinstall because I have too many settings in my browser that I don't wish to reset. Please solve the problem.

Hi, the turbotax website forced me to update Firefox and since I did, I am no longer able to open the browser at all. The error message reads, "You can't use this version of the application "Firefox" with this version of OS X. You have OS X 10.11.6. The application requires OS X 10.12 or later." Unfortunately, from what I have read, I can't get that update that on my iMac (21.5inch, late 2009) OS X El Capitan Version 10.11.6. Is there any way to downgrade the Firefox install? I can't even see what previous version of Firefox I had before because I can't open the browser anymore. If anyone can help I would be super grateful. Thanks in advance!

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

Hi,

My computer was on during the week-end and when I came back home I noticed we had a couple of power outages. Computer restarted automatically (Win 10 22h2) and when I launched Firefox, it started as brand new with all my addons gone and none of the previous session restored (I had 4 Firefox browsers opened with each 20+ tabs opened).

I have tried looking at C:\Users\MYUSER\AppData\Roaming\Mozilla\Firefox\Profiles but found nothing of interest. Where is everything and how can I restore everything I had ?

I even tried Troubleshooting mode and downgrading to a former version of Firefox (126.0.1 64 bits).

Thanks,

Hi - I updated my Firefox / Mozilla browser yesterday and now all types of downloads are failing. PDFs and EXEs alike. I can't an error that says Failed.

And yet, when I use Chrome or Edge, the downloads work fine, soooo - not sure what is going on.

Can you please assist? Thank you!

Firefox: 127.0 (64-bit) Windows 10

Hi everyone,

I run an online barber supply store called Magnus Supply (https://magnussupply.com/) where we offer a variety of products including clippers, trimmers, shavers, grooming products, accessories, and sanitation supplies. I'm always looking for ways to improve the user experience on our website and streamline our e-commerce operations.

Can anyone recommend browser extensions that could help with:

Enhancing website performance and speed. Improving user engagement and retention. Simplifying the checkout process. Better tracking and analyzing customer behavior. Ensuring data security and privacy for our customers. I’m particularly interested in extensions that work well with Firefox, but suggestions for other browsers are also welcome. Your insights and experiences would be greatly appreciated!

Thank you in advance!

Hello, I am currently facing a problem. Yesterday, I passed a message from https://firefox-source-docs.mozilla.org/setup/linux_build.html#building ---The official documentation for firefox on Linux compiles and installs a Linux system with aarch64 architecture on an Ubuntu host with x86 architecture. In fact, I only modified a file called ". mozconfig" and added the following information: "ac-add-options -- target=aarch64-linux-gnu mk-add-options MOZ-OBJDIR=@TOPSRCDIR@/obj-aarch64-linux mk-add-options AUTOCLOBBER=1". After compiling for a while, I obtained a folder called "obj-aarch64-linux". I used the command "file /obj-aarch64-linux/dist/bin/firefox" to check the properties of the knowability file as follows: " firefox: ELF 64 bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter/lib/ld Linux arch64. so. 1, for GNU/Linux 3.7.0, BuildID [md5/uuid]=6b1bede035b0d0bc9930d0d4d88c3c14, with debug_info, not stripped ”. I think I have completed cross compilation, so I compressed the "obj-aarch64-linux" folder on a USB drive and copied it to my aarch64 architecture development board. And when I tried to launch the browser on the development board using the "./obj-aarch64-linux/dist/bin/firefox" command, I received an error message saying "Couldn't load XPCOM". It is worth mentioning that firefox is installed by default on my development board, but I need to compile and install its source code, and local compilation cannot be achieved on my development board, so I made the above operation. So, I want to know how to solve this problem, or if there are any errors in my cross compilation process. Thank you for your help and look forward to your prompt reply.

I want replace firefox Windows Mozilla MSIX 1- 0 package browser from ms store with regular downloaded version but I do not want to lose all my settings.

How do I go about this?

Thank you!

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

I reinstalled Windows because my Windows got basically completely corrupted, I tried to log in to Firefox after reinstalling and it won't retrieve the bookmarks I had until 15 or 16 June, please help I can't get them back

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

How to download the format in the main qa of the is sangu question regarding your to show the subjective other in the same line you can't be in the same direction.

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!
