Firefox Support Forum

I'm using and old operating system on my computer, and the latest version of Firefox seems to overtax my graphics card, even with the most mundane websites and functions. So, I had to downgrade versions to the one just previous to today's update to even get here. However, it makes you create a new profile instead of using an existing one. Is there some way to get around this?

well, most ad provider let you customize your ad preference I can allow virtual realitity devices ads and "turn off" android apps or food delivery apps however, they will completely ignore those settings if they can't show me an ad for my prefered topics specifically, I live in a very backwater rural town, I've paid a good sum to ship my VR equipment from another state, so it would be nice to see some games I can buy from their store, but of course, because I live in a backwater town and they don't sell vr equipment nearby, they will attempt to show an ad for something I can but locally, and you guessed it, they show me ads for ifood and uber eats, despite me telling them to not show me ads for android apps or food delivery I don't mind the ads per say, but between a major annoyance and no annoyance at all, the choice is obvious and no, I don't want white-list websites on ublock, if I could, I would left all websites show ads, if they were actually interesting to me instead of random junk I can find on the app store

After the last update, when I read my local paper online, Firefox will not advance to the next page when I reach the bottom of the page. I have to manually click on the next page arrow. Two other browsers will still advance so I'm thinking it must be a Firefox issue. Please help

Firefox after PC restart was restored 1-2 month ago session, not the current. In history all visited sites saved, but I have old opened tabs instead opened before PC restart.

• I restart PC after heavy lags and total freeze.

And I have restart of PC before it and after this old sessions.

How I can restore the true current session? I don't want do searching all opened last week links in infinity links list.

Greetings. Marek.

i am filling out a pdf form from the canadian government, and it say javascript has been disabled. i need to know how to enable it to complete the form. i am using windows 10.

For only the past 2 or 3 days when I open Firefox, there is NO taskbar shown at the bottom of the page. It's just disappeared and I haven't changed a thing! I checked the settings in windows and it's set to permanently show the taskbar. Why all of a sudden the change and how do I get it to restore on Firefox. This is NOT happening with other browsers I'm using!! This is beyond frustrating. I don't understand why things change from day to day without my intervention.

When will we have Dark theme for all websites , like Chrome or Opera browsers? I know , there are some extensions for that ,but i prefer the built in option. Nightly version (since version 96.0a1) have got this feature , when will come to Stable?

On the opening splash page (when a new window has been opened) upper-center is the large firefox icon, then below that is the search dialog box, then below that is a series of icons (for me now, there are 8 of them). How do I add icons to this? I know how to remove, but I can't see a way to add the icons I use constantly.

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

My bookmarks toolbar is empty. When looking through the bookmarks menu, it shows that none of my bookmarks have been removed, and they are all still listed as being present in the Bookmarks toolbar, but they are not displayed in such. To be clear, bookmarks toolbar is enabled, and I have already verified its positioning in the customize toolbar pane. There is a strip of empty space where they used to be, but they are simply missing now. How do I fix whatever issue caused the toolbar to cease displaying my bookmarks?

ctrl shift p stopped working

I can click it to private browsing

tried developer mode w/ the add ons disabled and still does the same thing

Any clues?

Firefox automatically updated last night, and once again defaults to its own printer dialog box. I hate it. There is a link to use the system print dialog box but it only works for that specific print job -- which wastes a lot of time every time I want to print.

I can't find a setting to choose my system printer dialog box as default. the solutions from last year no longer work (about:config, then tab_mo, then print.tab_modal.enabled, set to false.

Anyone know how to fix this? It's enough to make me stop using the browser because the Firefox dialog box sucks.

Hello

I want to open pdfs from firefox (snap 101.0.1) with the default application of the system (Xubuntu 22.04) and not open them in a new tab within forefox.

But it does not work, as if there was a problem with the system handler but only for pdfs and not for other file formats.

More details :

• I changed Preferences/general/Applications for pdfs to use either "always ask" (and then chose "open" " With system handler" when asked) or "default system application". In both cases the pdf is downloaded but not opened. If I right click on the downloaded pdf in the list of downloaded files and then chose "open with system handler", nothing happens.
• Opening the pdf inside Firefox works well and opening pdfs saved on my disk (outside firefox) as well.
• Opening other file format by choosing to open them from firefox with the system handler works well too (tested eg with .torrent, .xls, .tif,...).
• I tried to change the default system application for pdf (Atril) to other softwares without success (Okular, Evince).
• If I try to open a .djvu file with the "system handler" it is opened correctly using Atril which is the also default for pdfs... So Atril works for .djvu files but not for pdfs...
• I tried to replace the handlers.json file from my profile by a handler.json file from a brand new profile, without success (I still have a backup of my old profile file if needed). I did that because opening with the system application worked before and the bug appeared after I changed all applications preferences to "always ask" (and there were a lot of them in my rather old handlers.json file).

I'm lost...

Earlier versions of Firefox allowed you to choose a website when opening a new tab. Now the only choices are Blank Page or Firefox home (default). I find neither acceptablee and would like to specify aparticular URL to open a new tab, same as the custom URL I have selected for the home page.

How can I do this?

I am trying to download a spreadsheet file which has a .xlsx extension. Firefox insists on downloading the file (my default action) but I want to be given the option to open in my spreadsheet program (Libreoffice).

Looking in Settings and scrolling down to Files and Applications -> Applications, there are other spreadsheet formats present but not one for .xlsx. How do I add the "Always Ask" option for .xlsx files?

Libreoffice is the default system application for opening these files.

I write in 5 different languages and recently something changed.

Previously a language selection worked like a Radiobutton, only one choice possible, if you selected a different language, the previous one got unselected.

Now that doesn't work anymore, if I switch on a language it get ADDED to the list, which is not helpful since typos in one language is a word in another.

So my complaint is that 50 times per day I have to first UNSELECT the current language, then re-enter the menu and select the wanted language, it sucks.

I'm sure there must be something to fiddle.
