Firefox 社群討論區

Hi!

I am getting messages that I am blocking ads for many of my internet requests. I had never received these before but all of a sudden I started to get them. I have tried a number of things but nothing works.

I am running Windows 11 and do not have any Ad blockers.

Opening PDFs automatically with Firefox and, without any changes I might make, saving them with the download function in Firefox, actually ruins the functionality and data entry function of that file. Specifically this happens with PDF files downloaded from the (not all that amusing) PDFs from the FINCEN, (US Financial Crimes Enforcement Network). I do not see why and how Firefox thinks it is allowed to change files that are simply downloaded and saved on Firefox.

In other words, it seems that Firefox strips away certain "permissions" and/or "functions" (like built-in lookup, menu or choice boxes). This means that the file so downloaded via Firefox can no longer be used to properly fill in data, or to look up and choose data items within the file. (I see many times that ANYTHING having to do with "permissions" tends to be an intractable and unsolvable problem for software makers & experts, so, if you do not know right away how to solve the problem, it will probably take you several years to figure this out.)

The PDF in question is created by a government agency. If you have ever dealt with a government agency, then you know that they act sort of like Adobe or Microsoft: "They don't respond, or they do respond & say they do not understand, and if they understand, they are either unwilling or unable to fix the problem."

If there is a switch or option within Firefox, which lets me tell Firefox "Save this file exactly like it is received, nothing added or removed!", that would be nice. I just have not found such an option yet, and it would be nice if it might get provided someday.

I will share my browser data, but I am sort of convinced that a detailed question like mine will not be addressed within that shared data.

Ich habe über die Sicherheitssoftware "Trend Micro Security" eingestellt, dass keine heiklen Daten wie Kreditkartennummer, Debitnummer, Kontonummer etc den PC verlassen, ohne dass ich zustimme. Nun bekomme ich, wenn ich Mozilla Firefox öffne, ständig die Warnung von Trend Micro, dass die Sicherheitssoftware verhindert hat, das Mozilla eine von den gepeicherten Nummern übertragen wollte. "Die Funktion zum Schutz vor Datendiebstählen hat verhindert, dass geschütze Daten den Computer verlassen." Angegeben ist das Programm "Firefox.exe". Was passiert da bei Firefox im Hintergrund?

Is there a way to set a default webcam so website gets access to the not-first-camera by default?

Firefox will ask me if I want to allow a website to access my webcam - I do want the website to access my webcam. But when I choose the correct camera (3rd on the drop-down) and click allow, it just prompts me repeatedly (usually 2-3 times per session, every time I visit the page) if I want to use the camera & have to repeatedly select the 3rd camera on the list. If I check the box to "always allow" then firefox defaults to the first camera on the list, which is a view of my desktop, not actually my webcam (because that's what the first camera in the list is used for - displaying my desktop).

What I want is to set a specific camera to always be allowed on a website, but NEVER let the website have access to the other 4 cameras in the drop-down list. I'd even be okay permanently disabling those 4 cameras from Firefox because I only use them with other applications. I only want firefox to ever use the 3rd camera in the list exclusively, but there doesn't seem to be a way to do that.

I have Firefox on two Apple devices- IP address location and speed is fine on one but IP address on the other is nowhere near where I live and the processing speed is very slow.This IP address appears blocked on some sites. I am not operating a VPN. Safari on the same machine works fine, with correct location and good speed. I have tried all the Fixes that I can find on line without success. Firefox is up to date.

All of a sudden I cannot check out using shop on my IMAC. It has worked for me for years and now all of a sudden it stopped. Not sure what settings to edit. I can go through the check out process, but when I press check out the page will not load. I just get a shadow & spinning like it's trying to upload but it never does. If I switch to Safari I have no problems, but I prefer Firefox. Any suggestions or solutions appreciated. Lorri

I encountered an issue when exporting a theme from Firefox Color. When I downloaded the XPI file, it contained only a `manifest.json` and **did not include the background image files** referenced in the manifest. This caused Firefox to reject the theme as “corrupt” when trying to install or import it.

What I discovered during debugging:

1. Firefox Color provides both a **ZIP** and an **XPI** download.

  The ZIP contains the correct folder structure and the background image files.
  The XPI is missing these files entirely.

2. Because the XPI is missing required assets, Firefox treats the file as corrupt.

3. Importing the broken XPI through the Add-ons Manager or uploading it to AMO also triggers corruption or validation errors.

4. I had to manually inspect the ZIP, extract the proper `images/` directory, and rebuild the XPI myself.

5. I ended up using ChatGPT to troubleshoot the issue, confirm expected manifest structure, correct extension ID mismatches, and verify JSON formatting.

The issue appears to be that Firefox Color’s **XPI exporter is broken or incomplete**, producing theme packages that cannot be installed or validated without manual repair.

It would be helpful if Firefox Color’s XPI export included all necessary files consistently and matched the structure found in the ZIP download.

I wrote about 15 mins ago. Just wanted to add that when I go to profiles and try to delete others, clicking delete takes me to a firef. standard home page (sans bookmarks) and nothing about the 3 flowers/finalizing the deletion!?

I am also concerned about this flower icon, on my mac dock...can't tell if that flower is an abnormality that it thinks my "orignal profile" is not the profile of main use. This isn't just aesthetics: it seems to be telling me if I delete the other profiles, it won't stop that freakin flower icon from KEEPING MY COMPUTER/F.FOX FROM SHUTTIGI DOWN?

All I know is, everytime I go back to manage profiles and open ancillary ones (e.g test 2, Mac 15 Air, etc) I end up with more firefox icons on the right side of my dock!

I am trying to clear some out dated stuff off my computer to make some room on my dreive, and have discovered several older versions of Firefox, saved in a file, Can I uninstall them or delete them - I am worried that this might affect my newer version.

I reinstalled my pc and when I log back my firefox browser, I can sync everything back, but not the content in my Notes extension, I really need that and can anyone help me how to recover those notes?

About 4 years ago, the Firefox developers apparently had their brains removed and decided that it was a good idea to couple the light/dark mode selection to the font used in the theme, which of course makes absolutely no sense other than to annoy the users. There used to be a workaround for this (see this thread: https://support.mozilla.org/en-US/questions/1366357), but as of the latest update the workaround doesn't work properly anymore. No matter what I try, some menus remain dark unless I switch to a light theme. This is completely unacceptable. Mozilla needs to end this stupid behavior asap, as they should have four years ago already
