Firefox Support Forum

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

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?

Hello community, As soon as firefox 106.0.2 finished installing itself i was greated with some nice new color schemes to choose from, and also some other settings regarding accessing content and tabs from other devices, retrieving closed tabs and so on. Ever since i can't seem to find and access those settings. Any ideas would be much appreciated. Thanks in advance. I'm on linux, Manjaro.

Hello,

Since recently the bookmark dialog has changed its behaviour, and to worse from my perspective. If I don't do anything for about three seconds, the dialog closes and the bookmark is saved to a place where I most likely don't want it to be saved. Is there a way to get rid of the three second time limit? Thanks!

It's not necessary to read further to answer my question. Bellow I'm going to give some criticism and express frustration about this new feature (or is it a bug?). The criticism is not directed towards the nice people here who give support to users who have problems.

I understand that developers get new ideas and want to put them into practice, but if you change an often used behaviour like this, I don't think it's user friendly to just change the behaviour without asking the user if he want's that behaviour. Personally I don't see how the automatically disappearing dialog helps me (it's very easy to click Esc if I change my mind about bookmarking a page), but I keep experiencing how it makes my browsing experience worse, as I often pause for a moment for example to think what name I'm going to give for the bookmark, or where am I going to place it.

In practice this change has wasted at least an hour of my time (to find an explanation and (in vain) a solution to fix the behaviour), made me annoyed, and based on the comments here and other places, made quite a few other people annoyed too.

Please, when you change the behaviour of Firefox in the future, before changing the behaviour for an individual user, ask him first if he even wants the change. For example show him a dialog where he is told that "we have this new feature where your familiar dialog keeps disappearing every three seconds for no reason so that you get the pleasure of invoking it again...and again...and again. If you want to have that feature, check the box on the left".

Subject line says it mostly. Normally, when you click a bookmark button it replaces the content in current window by default. I am aware I can hold CTRL or SHIFT down to launch a new tab or window respectively. I would however like to be able for certain bookmarks to set the default launch behavior, similar to setting the HTML target=_blank tag on a link. I need certain bookmarks to always launch into new windows (and even nicer would be to launch into a conveniently resized window to left or right of my current window). The idea is that there are frequently times when the content of both windows is needed at same time.

This appears to be confined to FX. (FX 110.0.1 (64-bit) on Linux) Elements like input or output are hidden if id the ID is set as "adv". What is going on - is this a gotcha? Easy workaround of course but that's not the point.

In my Bookmarks Toolbar I have created a Folder, 'News' and placed it at extreme left, next to the 'Show Your Bookmarks'. By clicking on the 'News' Folder I can see and select any of my favorite Web news sites. Very handy. Today, however, when I clicked on the News folder my 73-year-old hand accidentally dragged the News folder on top of the 'Show Your Bookmarks' icon and the News folder disappeared !! I can't figure out where it went !! Help !!

Hello. For the past few days, I am unable to access the content of some websites. For example, Reddit seem to load but the page remains blank. This happens on other websites, where I am unable to login although the page displays correctly (an error message appears on one of them: "Please check the consistency of your URL").

This is quite annoying, especially because I cannot find anything related on the web. I use Firefox on POP OS 22.04.

Thanks. Cheers.

Hello, there is the note for FF 102 Release:While Bug 1771084 does not represent a specific vulnerability that was fixed, we recommend anyone rebasing patches to include it. 102 branch

Patch 1 and 2. 91 Branch: Patch 1 and 2 (Despite saying Parts 2 and 3, there is no Part 1). To clarify, so the current 102 release of FF does not 'contain any patch for that bug 1771084, and it's recommended manually to install these patches? Or they are already incorporated in the release?

I often use two firefox windows each with several tabs opened

Problem is when I quit in this state sometimes only one of those multiple windows gets opened on the next launch

To quit I do a `ctrl + q` or right click `Quit` from launcher bar

Is there a setting to tell firefox to always relaunch with the same set of windows ?

I use sync and this happens when using the same computer for the exit then relaunch of firefox

firefox release 112.0a1 (2023-03-05) (64-bit)

Ubuntu 22.04

Firefox 110.0 64 bit on Linux Fedora 37. Happens with my default setup and also when running with extensions disabled. Default font. English Language.

If I got to this website https://www.endesaclientes.pt/uPortal2/MyEndesa/index.html#/login, right now, it is in maintenance mode. It's tab label shows up as "Em manutenção..." when it should display "Em manutenção". In case this text field munges my text, see image of the tab, and the letters between "uten" and the final "o" are supposed to be a c with a cedilla and an a with a tilde.

Do I need to change my configuration to add the proper font in tabs?

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

An automatic update of Firefox which resulted in a "quit/create new profile" choice has removed all my bookmarks

Of the four profiles stored in "about:profile" three are identical (ie. have only the default bookmarks stored) and one, generates a "quit/create new profile" message.

The "bookmarksbackup" folder (in /home/user/.Mozilla/Firefox/zs1jki8t.default) is empty.

The "import/backup" option (in Manage Bookmarks) offers nothing to choose. There is no 'list of dated automatic backups.'

Firefox did not create an "Old Firefox Data" folder on the desktop.

Browser privacy "strict". "Never remember history" was selected.

Running Firefox in Manjaro (Linux)

Help.

I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

This is my second request because I can't find my original question. jonzn4SUSE has asked me to upload print screens, which are attached. Carl ([email removed from public])

Whenever a website prompts for me to upload or download a file and I except Firefox crashes, quitting in its entirety. This still occurs in "Troubleshoot" mode so I assume it is not any of my extensions. Here is a crash report from when this occurred if it helps. Another odd observation I made is that I am able to upload a file if I use a "drag-and-drop" feature on a website.

I currently use Chrome on Android & Chromebook as my main browser, but I would like to switch to using Firefox now across all my devices (linux, android, chromebook). To do this, I need to import my passwords from Chrome to Firefox, and have them sync between the Firefoxes on all of my devices, but it's not working. I have tried the following:

Method 1: I installed Chrome on my new Linux machine. Checked and made sure it had synced my passwords by logging into a website using Chrome. Then, on Firefox, I pressed alt to enable the toolbar, then File->Import from another browser. The pop-up says "No programs that contain bookmarks, history, or password data could be found."

Method 2: Chrome seems to have a feature to export the passwords to csv. So I exported the passwords from Chrome to a csv on Linux. To be thorough (because I am having trouble getting this to work), I used accounts.firefox.com to sign out the Firefox on my android phone and chromebook, then (on the phone) I deleted my browsing data, uninstalled firefox, and rebooted the phone. Back on Linux, I did about:config, then set signon.management.page.fileImport.enabled to true, then did about:logins then menu->"import from a file", selected the csv that I just exported from Chrome, and clicked Import. Import Complete, 332 logins added, 1 not added because it was missing a password. Logins successfully imported, hooray! For testing purposes, I create a unique new password entry, http://foo.com username "a" password "b". Then I go to about:preferences, make sure that syncing is on and I'm currently syncing logins and passwords, and press "sync now". Log in to my phone, install Firefox from the play store, start it up, sign in using my email and password (it says "syncing"), go to logins and passwords, click "saved logins". The only one listed is for foo.com, the fake one I created to test the syncing, but I expected to see all 333 there.

How do I get this to work?

I upgraded to Ubuntu 22.04 recently. Since then Firefox 104.0.2 (64-bit) has been arbitrarily freezing; sometimes i have to restart the computer while most of the times I am able to kill the Firefox main process and restart Firefox.

The freeze occurs when i try to save a Web page; i don't see any "logic" as to which Web pages cause Firefox to freeze. It seems totally arbitrary.

I clear my downloads list everyday (sometimes more frequently than that) and clear cookies & cache everyday.

I have selected "no proxy" by default, in 'Connection Settings'.

This never happened until after i upgraded to Ubuntu 22.04.

I've browsed the support pages and don't find anything relevant to my problem. If I'm overlooking something, I apologize in advance!

I have attached a 'screen capture' image of Firefox processes just before i killed the main process.

Thanks in advance for any suggestions. Ramki

When Clicking on the xkcd random button, I am led to an error page, saying: """The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.""" This is unaffected by turning off tracking protection. This may be an error with the page Steps to reproduce:

- go to xkcd.com
- click on the button labeled "Random"

I want to know if there was any changes in recent tab cycling behavior? Now I need not press enter or click mouse button on one tab from list. Before there was instant tab changing after stop pressing keys (ctrl+tab). Greetings Kamil Tomicki

Hi, I'm using 0penlayers and with this online example : https://openlayers.org/en/latest/examples/export-map.html when clicking "Download PNG" button I get the following message in Firefox console : "Blocked https://openlayers.org/en/latest/examples/export-map.html from extracting canvas data because no user input was detected." And the image downloaded is incorrect. I have no Firefox user message asking for permission to canvas access. I'm using Firefox 107.0.1 (64 bits) Mozilla Firefox Snap for Ubuntu canonical-002-1.0

With Firefox on windows or android the example is working fine. On the example web page there is the javascript code using the canvas.

Bye !

Pierre.
