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.

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,

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.

Firefox won't update to version 127 on macOS 10.15.7

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!

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

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?
