Firefox Support Forum

I am very strongly opposed to any AI features being forced on me. When I opened Amazon today I discovered Fakespot had turned it self on. Might there might be some way to edit my config file to not have this happen again?

Similar to what @KW was experiencing here: https://support.mozilla.org/en-US/questions/1392858

I'm also having the same issue. I tried replying to that thread, but it's been archived.

I have two printers that were removed from macOS System Settings in Sonoma 14.5. They are showing in the print dialogue menu in Firefox 127.0.2 on both my laptop (MacBook Air M1) and desktop (Mac Studio).

Rebooting the computer, restarting Firefox, etc. haven't resolved the issue.

Firefox's PDF viewer incorrectly applies user-defined font settings intended for HTML pages, resulting in illegible PDFs and requiring time-consuming workarounds.

Key Points: 1. When "Allow pages to choose their own fonts" is disabled in Firefox settings, the built-in PDF viewer renders some PDFs with incorrect fonts, replacing characters with icons and gifs. 2. This setting should only affect HTML pages, not PDFs, as PDFs are designed to maintain the author's exact formatting. 3. Current workarounds (saving/opening PDFs locally or toggling the font settings) are inconvenient and disrupt workflow. (Open a settings tab, navigate to fonts, navigate to advanced, toggle the option, select okay, return to prior tab, reload, view without error, then repeat the process to restore preferred settings.) 4. Users who prefer custom fonts for HTML content are forced to choose between readable PDFs and their preferred web browsing experience.

Background: HTML is intended to decompose information exchange in such a way that the viewer has control of aspects such as fonts; while PDF is a format designed specifically to present exactly as the author intended. The difference is the primary reason an author would choose to use pdf vs html. The issues can be reproduced with B612 and other fonts, in Firefox 127.0.2 and many earlier versions, on github repositories pages that embed pdf files, and most other pdf files opened with the viewer.

Proposed Solution: Implement a separate font control setting for the PDF viewer, allowing users to maintain their custom font preferences for HTML content while correctly rendering PDFs with the author's intended fonts. Or, simply disallow the setting to apply to the PDF Viewer.

Impact: Resolving this issue will significantly improve user experience, maintain the integrity of PDF documents, and eliminate the need for disruptive workarounds, ultimately enhancing productivity for affected users.

I have a desktop and a laptop. Desktop crashed, so rebuilding.

Firefox on both, settings same on both. On Desktop - Last Pass will not appear. On laptop, same as it always has been.

Image below from my Desktop without the Last Pass icon there.

I've downloaded the LastPass Extension from Mozilla a couple times.

Help, please.

Very weird.

Just like title says, there's no download panel when opening a youtube video in a new tab. If i open it in the same tab, it'll show the download panel. How can i fix this?

My New Tab page has four rows of shortcut tiles, 8 to each row. Total= 32 tiles. I accidentally "dismissed" one tile and now the page has only 31 tiles. I can find no way to restore the setting for 32 tiles. I looked in the "about:config" file but cannot figure it out. Kindly help. Thank you.

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

Is about:config > app.update.auto set to false sufficient, How to Disable Firefox Update Notifications: A Step-by-Step

Or how about the registry? Turn Off Update

Settings > Home > New Windows and Tabs > Homepage and new windows

This setting got reset on me last night. Using 127.0.2.

So, I set it to custom, add in a URL, close the settings, re-open the settings and see it is set.

I close my non-pinned tabs and then close the browser.

Upon opening the browser, I am greeted with an empty tab and the Setting has reverted to "Blank Page".

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

I have lost recent activity on home screen. There are blank tiles but nothing is being added.Hovering over tiles nothing happens. How do I get recent activity to appear again ?

1. In the past there was a restriction on the suggested number for "network.http.max-persistent-connections-per-server". Is that still the case?

2. Does prefs.js contain all the altered about:config settings? Can I safely transfer "prefs.js" to other profiles in attempt to enable all those settings changes, instead of changing them manually, one by one.

Hello, recently I've been having issues where if misclick anywhere on the title bar (even in the small space between bookmarks) firefox will minimize/restore when I didn't want it too. How do I disable this in about:config?

I'm unsure about this setting. I don't want a tab to reload when it's switched to.

It seems to indicate that something will be reloaded regardless of what I choose. I assume that's probably not the case.

Please confirm.

Good morning, Our company's firefox add-on(Saba Security Plugin) has stopped working, please let me know what happened.

When a new client (version 126) downloads the add-on, the following message is displayed: "The add-on downloaded from this site cannot be installed because it appears corrupt."

If you install an older version, it works without any problems, what is the reason?

I have already contacted you once at: product-help@firefox.com

And they told me to report at: https://support.mozilla.org/questions/new/desktop/form

Regards,

I want to change "browser.sessionstore.resume_session_once" preference to true. So I do it in about:config page and if I reaccess this page in another tab within the session, then my value is being kept.

However, when I restart Firefox (thru "Exit" in "File" menu), all previous pages get restored and that preference is "false" again in the config after a new browser start.

I also made a user.js file with the following content: // user_pref("browser.startup.couldRestoreSession.count", 0); user_pref("browser.sessionstore.resume_session_once",true);

Nothing helps.

Please let me know how I can modify the config file.

Thank you!

Dear supporter, our firefox is managed by our company, while download file, not sure why some file type could not setup default option, due to no check box "Do this automatically for files like this from now on", could you share how to fix ? Thanks a lot.
