Firefox will only open in Safe mode, previously it was working but now it's not.

I have Ubuntu 22.04 Firefox version 99.0.1 (64-bit)

When I try to open it in command line, it's also only opening in safe mode but I do also get some error messages that I've included below.

So what does all this stuff below from the command line actually mean? And how do I fix it?

Hello there to all.. I have been experiencing occasional crashes on the tab when left idle for a while!! I am using Ubuntu linux 22.04 when this occurs..! In Windows 11 or even Windows 10 x64 pro this does not occur to my knowledge at all.. So I am wondering why this is happening only on ubuntu linux 22.04 and not anywhere else??.. Anyways, Thanks for listening and have a great day ahead also..

Thanks in advance!

Since I've upgraded to Ubuntu 22.04 "Firefox" randomly started closing it's self without any crash report what so ever.

I've read some article on Ubuntu forums but I couldn't find any helpful information (Or they didn't work for me)

Please anyone help! I've been using Firefox all the time and has never crashed until the upgrade to Ubuntu 22.04

Any help is highly appreciated!

Hello, I was trying to fix this issue on my browser but I was not able to do it. The OS is Ubuntu 20.04.3 LTS 64-bit. Currently, I'm using Firefox version 99.0a1 but I had the same issue on version 97. Also, I have this issue on only one of my PCs. As I said in the subject: - The browser freezes the whole PC and I have to force reboot it. (I already disabled the hardware acceleration) - the recent download item open button does not trigger the opening of the folder. - If I try to download a file, the browser ask me where to save it. But if I try to download another one the browser shows me the directory with path /run/usr/1000/... I tried to delete places.sqlite but I received the same result. ... I'm attaching two screenshots also. Thanks a lot!

Hello dear firefox developpers.

Recently i realized firefox is not saving cache where it used to. that happens some versions ago to now.

By a sudden necessity, i need to access images stored in cache by facebook.

however, firefox has moved its cache, and have no idea where it stores it now.

the second point, is, if there is any way of "surf" cache, im not sure but i wonder, the cache is not what used to be, a collection of files related to what you surfed in the web, videos, htmls, pictures, etc.

I seems the cache now works in a different way, making solid archives composed of many images-videos..., instead of separate files for every image-video.

So, in a brief, 2 things:

- where is cache now - how can i access files in it, (images videos ..)

PD:im using ubuntu 20.04 PD2:have a nice day, and thanks. PD3: trolls will be attended in office hours

how do I work with attachments in unbuntu? it greys out when trying to upload any attachments in gmail and outlook. I am new and cant find unbuntu help on latest update.

After a reinstallation of FIREFOX, it failed to login to sync with Firefox. My account and password input are correct. And I can login to my accout with Chrome (https://accounts.firefox.com/).

my OS: ubuntu 18.04 firefox version: 100.0.2

A lot of times while coding I press Ctrl+S to save Visual Studio Code and update live server (while watching on firefox the result). The problem is that when I'm focused on Firefox Ctrl+S pops up the Save Page window and (if I held Ctrl+S for more than a split second) it crashes (probably due to multiple popups becoming unresponsive). The mouse can't click to cancel the pop ups for saving the page nor interact it. I have to kill the firefox process and restart it. I've been looking into disabling Ctrl+S shortcut in Firefox with no success (extensions are deprecated or require too many permissions I'm not comfortable with).

Would someone help me to disable Ctrl+S or enlighten me on how to not have firefox crash every time I accidentally press Ctrl+S?

Thanks!

Clicking the back button does not usually take me back to Google search results. When I do a Google search and click on one of the resulting links, it's often (but not always, oddly enough) as if I've opened the link in a new tab with no browsing history. I can continue to click on links and build the tab's history, but the oldest url in the tab history is the one I got to after the Google search results page. To get to the Google page, I have to open my full browsing history.

If it's just my problem, I'll just keep doing that, but I appreciate any ideas. Maybe it's how Google redirects? Is there a setting that could affect this? Some of my settings are inherited from Ubuntu Studio.

Thanks.

Hi - I'm signed into firefox sync on two different computers, both running Ubuntu 20.04. I can tell that they're connected to the same account because I can see the other computer in the list for "Send tab to device".

However, the bookmarks aren't syncing - one computer has the full set, the other (newly set up) computer still has the default bookmarks.

When I check `about:sync-log`, I see these lines:

``` 1654551773179 Sync.Doctor INFO Skipping check of prefs - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping check of passwords - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping check of tabs - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping check of bookmarks - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping check of addons - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping check of forms - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping check of history - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping check of extension-storage - disabled via preferences 1654551773179 Sync.Doctor INFO Skipping validation: no engines qualify 1654551773179 Sync.Status DEBUG Status.sync: success.sync => success.sync 1654551773179 Sync.Status DEBUG Status.service: success.status_ok => success.status_ok 1654551773180 Sync.Synchronizer INFO Sync completed at 2022-06-06 14:42:53 after 1.48 secs. ```

That is, it seems to think that bookmark syncing is disabled - however, I have bookmark syncing enabled, as you can see in the attached screenshot.

When I open Firefox through the GUI nothing happens. It acts as if I never tried to open it.

When I attempt to open it via the CLI I get:

joshua@joshua-Z390-AORUS-PRO-WIFI:~$ firefox /snap/firefox/1443/snap/command-chain/desktop-launch: line 52: /home/joshua/.config/user-dirs.dirs: Permission denied sed: can't read /home/joshua/.config/user-dirs.dirs: Permission denied /snap/firefox/1443/snap/command-chain/desktop-launch: line 261: /home/joshua/.config/user-dirs.dirs: Permission denied cp: cannot open '/home/joshua/.config/user-dirs.locale' for reading: Permission denied /snap/firefox/1443/snap/command-chain/desktop-launch: line 266: /home/joshua/.config/user-dirs.locale: Permission denied Error: cannot open display: :0

For context: Ubuntu: 22.04 LTS

The update that I ran was simply generic system updates through the app store. Notably though it was the snap store not the ubuntu software store. Don't know if that matters.

Any ideas? Thanks a million!

When opening a new tab externally, e.g. via `firefox --new-tab <url>` or `xdg-open <url>`, Firefox doesn't raise its window.

If this behavior is abnormal, note that I'm using KDE on Wayland (Ubuntu 22.04) with "Focus stealing prevention" off. If it's normal behavior, is there a way to change it?

Reinstalled Firefox on Ubuntu 20 and signed back into my Firefox account and I don't have any of my passwords, bookmarks or extensions, I'm extremely upset - there's very important info I lost!

I'm using Firefox Version 98.0.2 on Ubuntu 21.10 with Wayland and Gnome 40.4.0. I choose a larger cursor size from Ubuntu's Settings->Accessibility->Cursor Size. However, in Firefox the cursor always displayed in the smallest size.

Hi, Downloading files to a system directory (Linux) such as /home/me/doc/here /home/me/doc/there Have Ask me where to save files checked.

But lastDir is not a real directory I can navigate, such as /run/user/1000/doc/3dcccd48

This causes the user needs to navigate sometimes very long system directory tree for each successive file download.

In about:config I set:

 browser.download.lastDir 
 browser.download.lastDir.savePerSite	false	
 browser.open.lastDir

But every time these are obfuscated to something like: /run/user/1000/doc/3dcccd48

This introduces about 10 user interactions with mouse/keyboard for each file I download in succession.

How do I get FF to stop obfuscating real system directories for "lastDir"

Really really appreciate the help :)

I run wxmaxima on ubunbtu 20.04. The help menu option calls up firefox (v 101.0.1 (64 bit)) to find the local on disk html files. However this brings up the error message:

File not found

Firefox can’t find the file at /usr/share/maxima/5.45.1/doc/html/maxima_singlepage.html#g_t_0025.

But this is a valid path with user access permissions and the file maxima_singlepage.html exists and has user read permissions.

So what is firefox doing in looking for this file?

I have used the ms windows 10 version of wxmaxima and the firefox help works perfectly.

Steps to re-create: create a new campagin attempt to change the display image using the hover-button over the image on the page.

What happens: I click the "change image" button, it gives me the os file picker. I select the file i want and click open and the file picker goes away. The "progress" bar at the top of the image shows up, changes through several states it seems. Then all screens freeze, and the computer stops responding to all output.

Supplemental info: This started happening after an update from ubuntu 18.04 lts to 21 to 22.04 lts. So I know I was not using a flatpak before and I am now.

I've attempted to use strace to figure out what's happening at the time of the freeze I'll include a picture of that if this form does not cause my entire pc to freeze. But didn't really get any useful info from that. I tried reading dmesg at the time of the crash but so far the screen freezes before any relevent information pops up. I've not been able to find any logs about whats going in previous dmesg logs.

Troubleshooting steps: I've attempted the same procedure in firefox's safe mode. This does not seem to stop the crash. I've attempted the same procedure using chrome and this works as it should.

When I click a link on a website, a new Firefox tab opens with this message: 400 Bad Request Request Header Or Cookie Too Large nginx/1.18.0 (Ubuntu). This is new behavior; it was working fine until yesterday. Can you tell me how to fix it?

While using firefox, the sizing suddenly has issue in minimize and maximize, this happens frequently under Ubuntu 22.04 LTS, never happen in Ubuntu 20.04LTS. The only solution now is open new window and move existing tabs to the new window.

Can refer screenshot, where you see the window at the back is missing a portion of rendering on the right. Is there any solution for this?

Years ago I imported a Firefox profile from Ubuntu 16.04 to a PC running 18.04. It wasn't very hard. View Hidden Folders, find the old FF profile, copy it. Then go to the 18.04 PC, delete or rename the existing profile, and paste in the profile from the 16.04 rig. Restart the PC, Firefox came up on the 18.04 PC just like it did on the 26.04 PC.

But Ubuntu is doing something different now. Firefox is inside the "snap" folder. Apparently snap is some sort of new package mgr. (?)

I found a firefox profile a few levels down inside the snap folder: Home/snap/firefox/common/.mozilla/firefox/xxxxxxxx.default

Does snap complicate things? Or can I replace the new profile on the 22.04 PC inside the snap folder with the profile that I want to use from the 18.04 PC? Just like in the past, but inside snap rather than the .firefox folder in Home?
