Fórum podpory Firefox

I just wrote this blog post and someone suggested I contact you.

I have my default browser set to Firefox on Linux (Debian Bookworm). When I open an http:// or https:// URL, it opens in Firefox, but when I open a file:/// URL, it opens in Chromium. It seems that file:/// URL makes it resort to the MIME type.

Is there anything Firefox can do here or is this a Debian or freedesktop.org issue?

Thanks!

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

After updating to Beta 122.0b3 (64-bit), the active tab is now highlighted with a simple white outline instead of the coloring surrounding the address bar. My selected theme has not changed, and the same goes for all of my extensions. I could not find this change in the 122.0b Release Notes.

If this behavior is intentional, is there any option to return to the previous behavior (including in about:config)?

This morning I could not log into the Schwab customer website using current Firefox version 123.0 on Windows 11. Reverting to version 122.0b9 solved the problem. Before the reversion I tried clearing cache, history, passwords, etc, and I tried a full reinstall of version 123.0. What else would prevent a connection to Schwab when other websites worked fine?

I have the following settings in Settings/Preferences>General:

Files and Applications

Downloads Save all files in the following folder: Downloads Ticked Ask every time where to save a file

Applications Portable Document Format (PDF): Open in Firefox How should Firefox deal with other files? Ticked Ask whether to open or save files

On specific websites when I click on a pdf link, Firefox opens and automatically saves the file to Downloads folder without asking whether to save and where to save despite the above settings. As far as I remember, on other websites when clicking a pdf link Firefox only opens the corresponding file and doesn't save.

I found this with a internet search https://connect.mozilla.org/t5/discussions/stop-saving-pdfs-to-downloads-when-viewing-in-firefox/td-p/10225.

How can it be disabled that Firefox automatically saves PDFs?

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

I cannot log in to my Gmail account via www.google.pl in the Firefox browser. When I try to log in via www.google.pl, the Bad Request Error 400 message appears. The same problem occurs when I need to confirm login to other websites using a Google account. I simply can't log in anywhere. This problem does not occur in other search engines. A login icon appears on the www.google.com website, but not all related services from Google are available - Google account, Google Play, Gmail, Meet, Chat, Drive, Calendar, and Photos are unavailable - these are just the most important ones that don't work. Cookies are enabled. On December 25, 2023, this problem did not exist. I tried to restore Firefox to an earlier installation date, but it didn't help. I uninstalled the extensions and plug-ins. Unfortunately, the problem remains. Please help me. Regards, Bogaczewicz Bogusława.

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

All of a sudden (started today) Firefox will not load ANY websites, except Mozilla/firefox websites. All previous bookmarks, links, and typed in addresses do not load. No changes to virus protection, browser, or any other updates. Other browsers (chrome, opera) work fine.

I must have pressed a shortcut to make this happen (Firefox zoom is default 100%), video is small and on the left, you can see that the progress bar is the same size as the video.

Thanks in advance :)

When I save new bookmarks I can't find them to open them. The list of folders I see in the "Choose . . ." selection is different from the list of folders l see when trying to open a bookmark. The bookmarks seem to be saving in one list but opening from a different list. How do I replace the list Firefox opens bookmarks from with the list the new bookmarks are saved in?

Firefox is my default browser. I clicked on a link in my email and it came up on Edge, and asked permission to open in Edge. I thought it was just for that link, but ever since, all my links are opening in Edge. I checked my computer settings and confirmed that Firefox is my default browser, but it doesn't seem to make any difference.

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

Hi. When Windows 11 was initially released, certain substantial feature of the Windows taskbar known from before was missing. I'm talking about 'Combine taskbar buttons and hide labels' and the option to set it to 'Never' (users tend to set it this way to always see the program icon along with it's label, not just the icon). At this moment, the feature has been available in widely released build of Windows 11 for months (Microsoft returned it after rewriting the taskbar code and after many complains), but it is not working correctly in conjunction with Firefox. When I close all windows and tabs of Firefox and restart the browser, only its icon is visible on the taskbar, not the label. Only when I open one more Firefox window, it starts to work as it should. Is it a known issue? Can we expect a fix to be made soon? Thanks.

So I've been doing this for years now, as a Youtuber I take an image file from File Explorer (Windows 10) and drag it over to upload the thumbnail to Youtube. But for some reason the last few days I can't drop the file, it just stays there with the mouse when I let go of the button. On a random page it should let me drop the file and show the image but it doesn't, and it also won't drop if I try a google image search.

I have tried this on Edge and Chrome and the problem only seems to exist on Firefox.

[My screenshot button hides the mouse in pictures but it's attached to that blue semi-transparent square, trying to drop a file but can't.]

Every time I open a youtube video in fullscreen, firefox crashes. `about:crashes` says "No crash reports have been submitted."

Some information about my system:

• Firefox version: 122.0.1 (64-Bit)
• Macbook Pro M2
• MacOS Sonoma 14.3.1

If there is a way to get more information that you would require (like logs) please describe how I access them, so I can share them.

Firefox is my default browser, but it does not allow me to log in to specific websites. For example, ihg.com, when I click the sign in button nothing happens, I just have a little note at the bottom left "javascript:void(0);" Another example, dutchcrafters.com , when I click Log in with Gmail, nothing happens.

I have tried removing all the content blocking extensions (privacy badgers, ublock origin, etc.), did not fix it. I have tried a firefox refresh, did not fix it. I have tried uninstalling and reinstalling firefox with several device restarts, did not fix it.

I know this must be a firefox specific problem because microsoft edge work perfectly for both of these examples. Any other suggestions to fix this firefox issue?

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

When Content Type PDF is set to Open in Firefox in Settings, some hyperlinks (see 'Download PDF' on https://arxiv.org/abs/2402.00923) will navigate to the hosted PDF without downloading to my computer. Others (see 'Download PDF' on https://www.overleaf.com/project/65c142c6d78ec5a8a34636b0) will download to my device then open the downloaded file in browser. (I am also interested in what causes this distinction in the first place.)

When it is set to Save File, both types of links will download to my device without opening.

In my experience with other browsers, the behavior is similar to the first case, but downloaded files are not opened upon finishing downloading, only doing so if the file is clicked on in the download menu during or after downloading. Is there any way to replicate this behavior?
