I am doing some web scraping, and i noticed a problem i am having. When i set the advanced preferences at about:config as such: print_printer = Mozilla Save as PDF and print.always_print_silent = true , then a pop up shows up and exclaims : The selected printer could not be found. If print.always_print_silent is set to false, then it works, or even if is true, if i set the print_printer as something else like: Microsoft Print to PDF, it works. Just the combination that i need isn't working. Is this a general problem or is it something else. Here are all my current customized preferences.

print.printer_Mozilla_Save_to_PDF.print_bgimages True

I would greatly appreciate you help.

Hello. I have few text replacement shortcuts on my macOS. It works in every programm besides Firefox. Even double spacebar that set dot (.) doesn't work. How to fix it?

I am having this same problem: https://support.mozilla.org/en-US/questions/1323092 except I followed those steps and gmail still opens in only the container I set for it. Even if I right click from a search and tell it to open in a different container or if it gives me a popup asking if I want to open gmail in the preset container and I click "no, open in this container", it will still open in the preset container. Attached is proof that "Always Open in This Container" is unchecked.

I did a clean install of Windows 7 on a new SSD drive. I transferred all the Mozilla/Firefox files (ver. 103) to new Windows 7 install. Appdata\Local, Appdata\Roaming, Application Data including profiles,chrome CSS. New Firefox has larger/wider tabs and the collapsible sidebar does not work, why?

my ASUS laptop was automatically updated to Firefox version 103. it now will not fit my screen. i cannot see the right hand portion of the page and cannot find a way to access it.

Latest version of Firefox with Windows11. After a day or 2, passwords are not filled in. About:config setting "signon.remember>Signons has flipped to false and "ask to save logins" and "autofill logins" are grayed out. Have disabled all add-ons and extentions. Site is Amazon.com - i have deleted it and then added it back. Firefox is set to "remember history" Does not matter if Firefox is closed down or not. Any Ideas?

I had to use forgot my password for my firefox account and now the sync option doesnt work for importing my logins.

What are my options to import all my logins? still have them accessible on another computer but trying to get them over to my new one. Also have the .csv file but that doesn't seem to work either.

There must be a way to import after changing a password right?

Thanks, Dan

Bookmarks and passwords have not been affected. Is this site data that may or may not be able to recovered? ... I am semi-proficient in finding folders, files and such....Thanks

Ever since the past four months of updates, the FireFox browser, when left open and idle for 4 to 5 hours leads to browser going offline and needs complete reboot of browser, and the lose of open tabs. Other browsers do not go offline, even when running at the same time that FireFox is open.

I have a "malware?" that continuously pops up on my screen and it appears to reference Firefox.exe and it has just started since my Firefox update on Friday.

It is titled Botnet and refers to a URL https://ap.lijit.com/rtb/ord?src=prebid_prebid_prebid_6.12.0

From what I can read it has to do with "ads".

I have checked my control panel/programs file and the only recent adds/changes are Firefox and Microsoft.

I want compact mode back! I had a theme that enabled it, now it's not working. Not only that, enabling compact mode in config didn't make it compact, nor did it give me the option to change densities in the toolbar under "more tools." What's even more aggravating is that Firefox has made all the elements too big so I feel like it's set for a low-vision user. I can't change the graphical aspects, changing the fonts did not help. Zooming out makes it too small. You ruined a perfectly useful browser. Are you sick of your job, or are you just stupid?

Without my doing anything, firefox has decided to download pdf files in its own html. I have changed the default to adobe rather than ask. When I open the downloaded file in adobe it comes down as an adobe file, I tell it to save as an adobe pdf, but it appears in file manager and then opens in firefox html. Worse, it, whatever it is, has gone into file manager and changed adobe pdf files, some of which have been sitting on my hard drive for some years, into firefox html files. How do I rectify this please?

I want to be able to open, say, pdf files and NOT have them saved in the downloads directory unless I mark them to be saved in the open dialogue. Firefox worked that way for years. I reported this as a bug, I think in V.101. After much palaver, some of it irrelevant, the bug was reported fixed, but it has not been.

The bug number — it changed frequently — I last noted down was 1738574.

Good evening.

Since Firefox version 103.0 was installed, it's no more possible to login to personal area of site www.repubblica.it.

It was always possible up to version 102.

Other logins work fine.

Thank you.
