Hi, I have firefox on my Ubuntu 23.04. When i start it it shows a black screen. I click quit on my system and then i startup and it lunches normally. What am I doing wrong or how to fix it?

I use Firefox sync between multiple devices, including a desktop and a laptop on Ubuntu Linux. This is done through a Firefox account. Both Ubuntu devices mentioned run Firefox 108.0 for Ubuntu 20.04 LTS.

I'm signed in on this Firefox account on my laptop (from which I'm writing this message). I recently (some months ago) changed my primary e-mail, since I may lose access to the older e-mail account soon. Now, suddenly, on my Ubuntu Desktop I received a message that I need to sign in to sync. When I click on "sign in", it takes me to tab that lists my primary e-mail address and asks for my password. I enter the password that I know is correct (it is listed under my saved logins on this Ubuntu laptop and the e-mail listed is the primary e-mail address with which I am signed in on my laptop, writing this message; it is also listed on my Firefox account details as my primary e-mail address). I then get a red message on tab stating "Primary account e-mail required for sign in", despite the fact that it is with my primary e-mail that I am attempting to sign in! I've tried it multiple times, to no avail.

At least two other users have posted about related concerns this year: (see https://support.mozilla.org/en-US/questions/1368875 and https://support.mozilla.org/en-US/questions/1395902). However, nothing has been done to resolve this issue. I have followed all instructions provided for changing my primary e-mail address. This is definitely a fault on Mozilla's side and not mine. Please resolve this urgently, users risk losing vast amounts of data, through no fault of their own, if you fail to do so.

I'm having a problem sharing websites with others via, for instance, Signal. Telegram, WhatsApp or a social medium. There used to be a share button in the toolbar, but this I cannot find anymore. At some time there were also the three dots in the address bar that dropped down a menu for the page, which included a 'share' option. These dots seem to have vanished. Also I vaguely remember that the "share" function was also in he tab context menu once upon a time. However dropping down that menu does not reveal any "share" function presently. Then there was, if I remember correctly, the possibility to click the File menu at the top of the screen and then click on the Share menu item over there. But also there the "share" function seems to have vanished. I also looked in the settings menu, to find if there is a setting there which switches on or off the sharing function. I could not find such a setting. In short, it seems that I am horribly overlooking the "share" function. Please help me find it. Thanks. (Firefox 112 for Manjaro Linux)

Sometimes when a a browser add-on is having trouble, I removed it, then hit undo, and sometimes it works again after that adds it back on. I thought I'd do that today since some were showing blanks instead of their icons. I did one from the manager just fine, but when I removed one from the toolbar instead of the manager, no undo option was presented, and I don't recall which it was. How can I undo, or view recently removed extensions?

For quite some time now I've had keyword.enabled set to false in my about:config because I don't like having the address bar try to autocomplete or turn things into search, when I do a ctrl-l.

I do like that I am still able to use ctrl-k to do a search when I need to. This would place a ? at the start of the field and whatever I type gets sent to search.

In a recent upgrade, ctrl-k still places the ? at the start of the address bar but doesn't send things to search. Instead, it now behaves as if I did a ctrl-l and typed in a bad URL.

I'm on Firefox 80 (on Fedora 32) but I can't be exactly sure which upgrade brought this change in behavior.

Is there a way to get the old behavior back? ctrl-l to enter a URL, ctrl-k to search.

Hi! Does anybody know how to disable browser closing by ctrl+q shortcut? It is too close to ctrl+w and sometimes I close the whole browser instead of one tab. Moreover it is really useless and stupid feature since I have alt+f4. Why I need another shortcut which do the same stuff? And why developers ignore this issue which was reported on several forums? I tried install extension which disable it but it doesn't work for me.

The question at the following URL has an answer that is no longer the best answer, but it is Archived and I cannot provide the better answer. Since "How can i reset 'container defaults' in FireFox Browser? I.E. I previously selected to open a certain 'site' is a specified 'container' - now I want to clear." is the top hit when I look for this on Google, I'm attempting to provide the answer here.

Clicking "Show more comments" on Facebook does nothing (I browse it without an account), also no comments are shown in Cracked.com, I haven't noticed if other sites don't show comments. I use Ubuntu 20.04 (when I first opened FF on this pc it had the gnome icon and I hadn't checked for this problem before importing my old profile with add-ons, now it doesn't show the icon for some reason), I tried safe mode, refresh firefox, creating new profile, uninstalling and deleting home/.mozilla folder, no luck. Before I got this pc I used my old laptop with windows 7 and I'm pretty sure I had the same problem with facebook comments that had started some time earlier.

debian Linux 64bit,firefox 87 is fine. It's a problem with 88.0. try: firefox https://bing.com I can see the title changed,but blank webpage.

try: rm -fr ~/.mozilla run firefox 88.0 , same thing happens.

I have Firefox installed on an XUbuntu 20.04.2 LTS machine. preferences to "restore previous session" on startup. Intermittently, when I launch the browser, one of my windows has a very strange appearance (please note the general look of the window in the attached screenshot and ignore the "page cannot be displayed" message, as the screenshot was taken when I was not connected to the Internet.)

I have already tried reseting Firefox and that does not make the problem go away permanently; it always comes back eventually. (Note: I cleared cache before, and cookies after, taking the screenshot but before opening this support request. So the "troubleshooting information" attached reflects how it is after cookies are cleared.)

Hi, I just discovered a problem setting secondary email when both primary and secondary is on the same domain, gmail.com.

Following the instructions:

Set up secondary email

The error that come up says that the secondary email must be different than my account email, but it is, the only common thing is the domain.

So this is a bug, please fix.

I am the webmaster for a church website. As you will see about the collected data on my computer, I work on a Linux computer. Because of the pandemic, the church has been worshipping using livestream video run from the church's website. To aid parishioners with the service, we post pdfs of the Service Bulletin, Readings for the Day, and other aids to participate in the service.

Up until, I think, Firefox 87, in testing the webpage before publishing, I was able to open the pdf links in a new tab. Now, when I try to test the pdf links, Firefox prompts me to save the pdf and I cannot view it online. Given that the pdfs were generated on my computer and exist in my files, It is somewhat ridiculous that I'm being prompted to save the pages.

However, because I also have a Windows machine, I know that this is not happening on all of Firefox, just on the Linux version,

How can I alert Firefox to get this fixed. When I'm not acting as a webmaster, I have occasion to click on a pdf link and it is annoying that it will not display in the browser and and opens up a "save" box.

Dear Mozilla Community,

I would like to know when Firefox will be dropping Windows 7 support? I readed on some websites that Google Chrome will be dropped support for Windows 7 in 15 January 2022 year so I would like to know if there are any plans by Mozilla Developers to drop support for Windows 7?

I don't have computers with Windows 7 but my friends asked me about this because they know that I am active community member of Mozilla but I can't answer because I don't know so this is why I asked you today about this.

Yours faithfully, Piotr

Hello,

I recently was forced to change the address of my blog from "universalism.com.au" to "universalism-au.com" (due to silly legal requirements introduced a few months back about requiring an ABN if you want to use the .au suffix).

"universalism.com.au" is now a dead link, but when I start typing "uni..." in the address bar, it always autocompletes to this old and depreciated url rather than my new one. I would like to be able to type "uni..." and have it autocomplete to the new address, "universalism-au.com"

I have cleared what seems relevant from my browsing history, but no luck. Is this perhaps being caused by my default search engine (duckduckgo) recommending the wrong address?

I have attached a screenshot if this helps.

I am suffering from slow load times -- especially the first time when the firefox is loaded for that day. Likewise there is a big pause when I go into settings -- saved usernames/passwords. Over the years I built up thousands of these pairings..

How can I easily remove all the old ones - say a year or older?

Please don't say, select the one, click delete, answer to are you sure prompt etc, as these actions take ages to do one at a time.

I have a problem with some JavaScript code that is run on a hashchange event.

The code updates the web document, and also the document.title. The document.title is modified last.

If not modifying document.title, everything works fine. If updating document.title, the code sometimes fails, but not always. The symptoms are as follows.

• The document.title is updated correctly, according to the A-tag with the hash URL that was clicked.
• The URL field in the browser is not updated to the new value.
• Non of the other document updates are done, even if they are performed on the code lines before changing document.title.

If a move the mouse outside Firefox and click in another window, the browser URL field is updated and the rest of the document is updated.

I then tried the code in google-chrome. There everything works fine.

If I add a console.log() in the hashchange eventhandler, everything works fine. Another work-around is to use window.setTimeout and delay modification of document.title by e.g. 10ms.

Is this a problem in Firefox, or am I not supposed to modify document.title on the hashchange event?

I am using Firefox 88.01 for Fedora 33.

I guess I should not include HTML and JavaScript in this editor?

I discover that when I disable history in security param and reboot firefox it deactivate all add-on from working on tool bar. Firefox Ubuntu 88.0.1 (64 bits) Ubuntu 21.04
