Backup & restore information in Firefox profiles

Hi there!

I'm attempting to migrate my Firefox (106.0.3) profile from the Linux Mint V20.3 on one SSD to a new installation of Linux Mint V21 on a separate SSD. I'm using the information supplied on this page:

https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Step 4, under Backing up your profile says: Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.

This folder, qspfoqtl.default, contains 1 file, named times.json, the contents of which are:

{ "created": 1618792039414, "firstUse": null }

Clearly, not my Firefox profile.

There is, however, a folder named nnob5aww.default-release that contains a bunch of directories and files (505.4MB) with names like bookmarkbackups, browser-extension-data... storage, weave.

Is this documentation incorrect as of this release of Firefox? And, should I be using the nnob5aww.default-release folder as the profile? I'm a little confused. (Most often, I'm a lot confused.) Any help would be appreciated.

Thanks in advance,

- Ralph

FireFox: 107.0 (64 bit) Mozilla FireFox for Linux Mint OS: Linux Mint 21 Cinnamon

Issue: On this FireFox latest version, the download window cannot be resized to smaller than (roughly) 1/4 of entire screen. (screen-shot attached.)

Attempted: Mouse left-click grab of all corners & sides to drag window smaller - failed!

Note: Download window can be resized *bigger*, showing this window has now been coded with a very large minimum size that is almost 1/4 of full screen

- this was not the case in previous versions.

Micro-annoyances add up, people switch to Chrome (sorry to use the "C" word!)

While exploring about pages in Firefox, I came across about:profiling. I'm not sure what exactly it does, but since I've been to it, a profiler icon has been added to the toolbar and I can't find any way to get rid of it completely (only ways are to hide it). If it could be added, there must also be a way to remove it? How can I close it?

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

  • Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

  • Ubuntu 20.04 LTS
  • Firefox provided by APT repository
  • Xorg display server

Not working in:

  • Ubuntu 22.04 LTS
  • Firefox 99.0.1 provided by snap
  • Wayland display server
  • File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

  • Firefox stopped being able to open file picker dialogs
  • Right clicking an image and selecting "Save Image As..." does nothing
  • With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
  • File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
  • No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

Things I tried that did not work:

  • Disabling hardware acceleration
  • Starting with add-ons disabled
  • Troubleshoot mode
  • Clearing startup cache
  • Clearing cookies and site data
  • Clearing history
  • Refreshing Firefox
  • Creating and using a new profile
  • Deleting the `xulstore.json` file from the profile directory
  • Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
  • chmod 777 ~/Downloads
  • Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

  • Why this fixed the problem
  • Whether I should be opening a bug report either against Firefox, or Ubuntu
  • Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

After updating my openSUSE Firefox package from version 122 to 123 every frame inside each window started to have weird grey overlay of scrollable area. I failed to find any description of such a thing happening, let alone how to get rid of it. I tried removing build-in distro-default preferences and had complete audit of all my custom preferences in about:config but none changed that behavior. I even updated to 124b4 but this also haven't changed anything. Naturally, nuking entire profile is not an option, I might as well replace the whole browser. So, how do I get rid of this thing?

Hello,

For an unknown reason, my firefox sometimes is really slow to startup.

It can take up to 10 minutes before the webpage start to load. My hardware is not that bad. I try to use the "performance" to capture the issue : https://share.firefox.dev/3x2rgHj I don't know if there is something to see because, the tool is also slow.

It happens on 3 different computers on linux.

I try to disable all extensions and without telemetry but nothing change. I'm reporting the problem now but it's much older

If you have a idea to fix this issue please share because it's really annoying.

I am using firefox v104 on linux mint. This problem happened this evening. Every tab i open shows the same error.

I tried the solutions suggested in other similar forum posts like >safemode (tabs still crashed) >driver update (my drivers are up to date as far i can tell) >deleting cache and reinstalling firefox (tabs crash). I took a backup of my bookmarks and extensions as suggeated in another forum post. > one youtube video (https://youtu.be/F9VaXwSB_po) suggested toggling media.cubeb.sandbox in the config section. The tabs started loading after that but it wasnt that useful as i wasnt able to get any videos to play in the browser.

Also, i don't really know if the issue is related, but chrome tabs were also not loading or responding ('Page unresponsive' error).

Please help. Thank you :)

On Google Docs, the very useful shortcut "Alt+/" for executing menu actions by name exists, similar M-x in Emacs or Ctrl+Shift+A in PyCharm or Ctrl+Shift+P in VS Code.

On a German keyboard, there is no "/" key. In Chrome the hotkey "Alt+#" works instead. In Firefox, it does not.

This hotkey is particularly important, because it gives quick access to menu actions, that have no hotkey assigned, or for which the hotkey does not work on the current layout.

Is there something I can do to make it work?

Note. Based on what I know, I cannot tell if this is an issue with Firefox not sending the Alt+# key correctly, a special feature of Chrome that isn't present in Firefox, or a cross-browser compatibility issue of Google Docs, that should be blamed on Google Docs and not Firefox.

Firefox 114.0.2 (64-bit), running on Open Suse 15.3, 64 bit.

Prior to Firefox 116, I could have the normal scrollbar up and down buttons showing by making:

widget.non-native-theme.gtk.scrollbar.allow-buttons True

But now it seems to have no effect. This is under Linux/Mint/Cinnamon. Also, now long-pressing is doing smooth scrolling (I never want smooth scrolling anywhere) and can't find a way to stop that.

I have these set from before:

widget.gtk.overlay-scrollbars.enabled false widget.non-native-theme.gtk.scrollbar.round-thumb false widget.non-native-theme.gtk.scrollbar.thumb-size .85 widget.non-native-theme.scrollbar.size 14 widget.non-native-theme.scrollbar.size.override 14 general.smoothScroll false general.smoothScroll.other false general.smoothScroll.lines false general.smoothScroll.pages false general.smoothScroll.pixels false general.smoothScroll.mouseWheel false mousewheel.system_scroll_override.enabled false toolkit.scrollbox.smoothScroll false ui.scrollToClick 0

Any suggestions appreciated.

Seems like it is always a fight retaining usable scrollbars in Firefox that do not hide, do not change size on mouse-over, do not "warp" on left click, do warp on center click, have a thumb that shows page size, have a background that is not white, and are not microscopic in size! Just call me "traditional"  :)

Thanks

Hi all. Did a search but found nothing that helped. Just updated my Fedora 36 workstation and tried to play videos in CNN and MSNBC web sites and get the error message: "Code: 4 | Message: Something went wrong during native playback." I am using the latest Firefox WEB browser. UTube videos are playing fine. Someone has stated on the Fedora forum that they have the same problem but has no problem in Chrome on the same machine. Any ideas? Thanks in advance. Bob BTW, this happened in two machines running Fedora 36 and Firefox 101.0.

I use the Feedbro-Addon, which creates an own tab. Its url is: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html

If I use it as a normal tab (instead of a pinned tab) ... it survives a Firefox restart. But if I use it as a pinned tab (which I want) ... it disappears after a Firefox restart.

I suppose it has to do with it being an addon-page instead of a "normal" page.

Is there a way to make it stay permanently pinned?

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

I installed one of the ad blockers, I can't remember which one. It's given me so much trouble that I thought to disable or delete it. I deleted the little icon ( a stop sign) that shows up on the far right of one of the menu bars (don't know the name of that bar but here it's the second one down). But websites still complain that I have an ad blocker. I've gone to 'add-ons and themes' but I can't find it. BTW, what's the difference between an add-on, a plug-in and an extension? Which one of those are ad blockers? How can I see and then delete whichever blocker I still have? Without the icon I can't even disable it for individual sites.

Hi there! I am a long time Chrome user and decided to try Mozilla Firefox. I loved it and after a bit of tweaking, I run into a problem I can't deal with myself. In Chrome I loved auto fill options every time I needed the option for my home address, email address or credit card. In Firefox I just can't do it. The option is only available for Canada or SUA. Is there any way I can make it work? Of course, I looked for some add-ons and actually found several, but given the fact that auto-fill in my case deals with personal and sensitive data, I need a safer method. Is there any? Thank you!

Firefox 115: menu and tabs background color changed

After Firefox upgraded from 114.02 to 115 menu and tabs background color changed:

FF 114: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2023-07-05-17-00-30-1a3adf.png FF 115: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2023-07-05-17-00-34-cba7e0.png

These are screenshots of active window. When window of v115 becomes inactive, background color changes to lighter, but still no visible horizontal line between menu and tabs. I don't use any additional themes, "System theme — auto" is selected.

From release notes for FF 115: For users with a Firefox Colorways built-in theme, the theme will be automatically migrated to the same theme hosted on addons.mozilla.org for Firefox profiles that have disabled add-ons auto-updates. This will allow users to keep their Colorways theme when they are later removed from Firefox installer files. I guess it is relevant somehow, but i never installed Colorways and don't know what is it.

How to make FF 115 look like it was in 114? I can see changes in `browser/themes/` in sources between 114.02 and 115. Is it possible to "extract" default theme from 114 and install/apply it to 115?

I use Firefox under Fluxbox window manager in Arch Linux, if it matters.
