Firefox supportforum

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?

Good afternoon. I just made a clean install of Ubuntu 22.04 in my system. I use Firefox, to navigate, study and download diverse things, including work files. When I tried to download those files in my google drive, it shows me the folder which I will use, everything right, but when I hit "Save", nothing happens. Do you know which is the problem? I can access drive from "files" from Ubuntu without problem, upload and download files... Thanks in advance.

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!

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

I accident clicked delete download when from my downloads list in firefox and I can't find it anywhere on my computer? Does anyone now how I restore this file to save the time having to re download it? I am using Ubuntu.

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

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.

Hi, I'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.

EDIT: the issue was solved by installing the following packages, as shown in this question :

xdg-desktop-portal xdg-desktop-portal-gtk

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?

To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

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 :)

My OS is Pop! OS. Using 'Tidal' as a web based music streaming service and I play vids on YouTube. Every time a new song or video starts, or when I skip, rewind or do anything like that, it auto resets the volume level output in my sound settings to about 75 to 80 % of the max possible level. So basically, I have to adjust each and every new song by hand, it is infuriating. I block facebooknet in Umatrix and firebaseinstallation googleapis as well as google tag manager but nothing else. That's on Tidal, similarly I do not block essential cookies on YouTube, so I don't think that is the problem. I have a hunch that the answer is somewhere in about:config. If this is intentional, then I'm giving up hope. Thank you.

Starting today, with firefox 102 (on Ubuntu 20.04), I cannot open a url using the address bar. If I enter a url and then hit Enter, it brings up my selected search engine looking for that url, not opening the url itself. This has not happened before today. Is there a way to use the address bar only for opening addresses, and use the search bar for searching?

Noticed geo.provider.network.url setting in about:config no longer works in firefox 102.0 ubuntu. I use it consistently so it was easy to notice that it no longer had any effect after updating.

tested both on https://maps.google.com and https://browserleaks.com/geo

Is it possible to revert to an older version without losing my data?

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

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?

I had a version of firefox working. The world was sweet.

One day (1 July or there about) things changed and firefox was basically useless. When I load it, all logins are forgotten and I have to log in again. (Painful, and another thread)

That aside: The "new" version was 102.0 This was applied to my machine without me knowing. (This also happened on another machine I have but luckily it didn't suffer the same problem.) But anyway...

The machine now has 102.0 installed.

The other day while trying to find what is "broken" in it, I am told there is an update and it told me I had 13 days to do it.... Or something like that. Alas I've deleted the screen shot as I need to keep the bin less full to help me if I accidentally delete something I shouldn't.

So now I have 102.0.1

So I'm confused: What is the mechanics of rolling out updates? An update I didn't want (beside the point) but none the less broke firefox was done without my knowledge, and yet another one which was throwing up messages at me when I loaded firefox doesn't?

I don't really know what either update did.
