Firefox Support Forum

PSA:

The snap version of Firefox (as implemented in Ubuntu Desktop 22.04) will not open a Zoom meeting link.

The alternatives are: - Google Chrome, etc. - Borrow a Windows machine and log into your meeting there.

What a disaster.

Hello,

I'm using Firefox 91.4.1esr (64-bit) from Debian repositories on Bullseye. Every time I open Firefox, a window with a greeting message appears ("Say hello to a new Firefox"), and it doesn't matter if, as asked by that window, I choose a theme or not. Is this issue related to my settings? Is this a Debian issue? Is it possible to stop that window from reappearing?

Thanks in advance. And many thanks for making Firefox (I've been using it for so many years I can't recall when I tried it for the first time).

I no longer have the option to watch BBC iPlayer as a picture in picture. The toggle switch has disappeared. I've tried hovering over various places on screen, but nothing appears. I've also tried right clicking to check it's not 'hidden', but it appears to have gone altogether.

I've checked and I have a least version 75 of Firefox (that BBC say I should have) and that the box is ticked in the browsing settings to enable P-in-P. Other streaming apps work (eg Discovery+ and YouTube etc).

Not sure is this is a Firefox issue or BBC iPlayer issue.

When I watch a video, mostly in Netflix, and go to the fullscreen mode, I see a url line on the bottom left corner of my screen. It doesn't go away when I click the screen. When I try to click over it it switches to the right bottom corner, which I find quite frustrating. Whenever, this happens I should refresh the page and hope that it solves my problem and most of the times it does. However, I still would be quite happy if I figured out what caused this problem and if there is anything I can do it to fix it for good.

Firefox version: 100.0.2 (64-Bit) Windows Version: Windows 11 Pro 21H2.

For at least the last few months, I've been having problems with printing. It doesn't matter if it's a web page, an attachment in yahoo.mail or a return label from Amazon, the print is too big to fit on the paper. If I switch to Edge, it comes out fine. I have used Firefox for years and never had this problem till now. Please help.

As of this morning, the Firefox browser on my work computer does not get access to any website - including mozilla itself. On the same computer Safari works without problems, on my smartphone and in the same wifi network my mobile Firefox works.

What is wrong?

moz back up says my profile is corrupted. my emall works in every way, but when try to use moz back u to make a back up it says my profile is corrupted . Can someone tell me how to fix this ? Or can someone tell what I can do that is better ?HELP!!!!!!!!

Hi there! Well, another company told my business partner that their product does not like Firefox so we should use Chrome and maybe Edge. First, that is a crock, but seems to be a standard answer from anyone in the business world, sadly. I would not trust Edge or Chrome, especially those two, if they were the last platforms on earth. So, help pretty please?

Is there a setting that we can use that will assist in using RSMeans Online Version so it will work more effectively? Whenever we get an error message or it just won't open, they blame it on Firefox.

I tried printing in FIREFOX while using PDF and receipts from Amazon and HP. each time the fonts are HUGE, but not if I use Chrome or Edge. Tried your suggestions and that didn't help. I see another user has had the same exact issue with no avail. I'd really like to get this issued fixed. I like FIREFOX and want to use it whenever possible, but being unable to print makes it a problem. I would appreciate a real solution. Thank you in advance, Alan.

I can't seem to open certain links - especially in Gmail if I click on a link it won't open. Anything that requires me to upload from my computer - it won't bring up the dialog box. I can't download PDF's from Firefox. I then have to go to chrome to do the same thing without a problem.

This issue only started happening once I updated Firefox 3 weeks ago.

Every day I am interrupted by McAfee with daily notifications across my screen saying they have detected a virus and to sign up with them. I have NEVER been a customer of McAfee and would like these nuisances to stop. Is there a way I can ban them from my pc. Thank you.

Hello.

Using FF 100.0 on Win 10. When I click a link to something that I don't want Firefox to open, like PDFs, I get the "What should Firefox do with this file?" dialog. If I select "Open with," as I usually do, the file opens in my selected program, but still downloads to my desktop. Some filetypes just open, I don't get that dialog. Those download to my desktop as well.

I've not noticed this behavior before. Maybe I inadvertantly changed a setting. Can someone tell me how to stop this from happening?

Thank you.

When opening History the column headers are there but no dates are shown in the Added and Last Modified columns. These columns are selected in Views and the listed web pages appear to be correctly sorted into Added date order. My browser is up to date an is 100.0.2 64 bit. Thanks

When downloading files from within Firefox, the option "Always ask you where to save files" seems to have stopped working recently. (Since version 98 or 99.) Sometimes it appears the selected files don't download at all, and other times it looks like they get downloaded to the Downloads folder. Still others, especially .pdf files, get downloaded to some unknown location, and then get opened in another application. I experienced no problems up until just the last week or two.

Hello,

When I select text in Firefox the selection is not highlighted. The selection itself does work (e.g. deleting a selected word) but is not visible. The problem occurs in all fields where text can be entered, so the URL space, the search field but also text field on a page like this one. The strange thing is that the problem also occurs in Thunderbird.

I am using Ubuntu 18.04.6 LTS, Firefox 99.0 and Thunderbird 91.8.1

Hi, I've just spent all day trying to follow all the different suggestions here regarding these issues. Adding all sorts of things to the userChrome CSS but 95% of the suggestions have no effect at all [I'm seriously non-technical, so I have no idea if I'm doing it correctly though...probably not] The only thing that I can change is the Tab Height...nothing else changes regardless of what numbers I put in there. The only way I've been able to make the Bookmarks folders usable at all is to enable Compact mode via about:config. But that actually makes it way too compact now...from one extreme to the other. At least it's usable now...so not the end of the world, but the right click menu still has way too much space between every entry [Compact mode made no difference to that at all]. I don't know how to make a screenshot of those menus :) so I took a couple of pics of the screen...can someone please show me what to add to the CSS file to make these ridiculously big spaces between the menu items way smaller...like they used to be before this Proton came in? I tried tons of things that people said to add to the CSS to fix this menu spacing thing but none of them changed anything. I'll include the CSS file that I have below. Thanks a lot

ps: for some reason the pics always come out sideways here
