Firefox 技術支援討論區

Firefox has been saving images from some sites as webp instead of JPG for a long time. There have been repeated threads on this subject which get locked and then pushed into the long grass.

Sure, I could botch a solution by installing an add-on to convert them, or I could use something like XnView (which I do, periodically, and in bulk) after the save event has happened, or I can edit about:info to tell Firefox not to accept webp - but this breaks functionality for some sites (like eBay), but I have found that in the end I have had to start switching to Microsoft Edge to do my browsing for a number of sites because Mozilla Firefox are ignoring repeated user requests to provide a simple option to STOP doing this.

I don't want to save any files as webp - save them as PNG if you like, or jpg, but I use an ancient copy (v3.24) of ACDsee (from the days of Windows 98) for my image browsing, sorting, viewing etc because it is perfect, blisteringly quick, has no extra editing or other functionality which I don't need or want, and it doesn't bloat up anywhere with thumbnail files... but sadly webp didn't exist back then so it doesn't support it. I have used a number of much more up to date browser-viewers, but there is nothing can touch this OLD version of ACDsee for basically brilliant design.

I'm not changing my image viewer. It's non-negotiable.

I WILL however change my web browser if I have to, if the developers of the browser continually kick into the long grass to lock, hide away and pretend there's isn't an issue which has been repeatedly flagged as an annoyance for so many users.

I have been using one form or other of 'Mozilla' family of browsers since the days of Quarterdeck Mosaic. I don't particularly want to switch my loyalty, especially to Microsoft, but if they are listening to what customers want and providing it, and Mozilla are not, what else is there to do ?

I am a retired systems developer. I cannot envisage this being SUCH a big ask.

Modern software treats its users like idiots and takes away control, doing everything it's assumes on their behalf that they will want.

It is not difficult to provide an option within settings for when saving webp files to save as webp, png or jpg with conversion if necessary. All you need to do is hear the screams and respond. :)

I was following this reddit thread on how to remove the "your camera and microphone are being shared" popup, but it's having no affect.

I have set `toolkit.legacyUserProfileCustomizations.stylesheets` to true.

Here's the full contents of the userChrome.css file: ```

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#webrtcIndicator {
  display: none;
}

```

When I download a file and click on the downloads button to bring up the Downloads menu, I often just want to open the Linux Mint file manager in the right folder so I can move the file to a more appropriate place.

In the menu, there's the little button to the right of the listed downloaded file with "Open containing folder", but if I click on that, FF opens the downloaded file, not the file manager.

Obviously this wasn't always like this, but I don't recall doing anything that might have caused the issue. How can I set FF back to the default action of opening the Linux Mint file manager?

Thanks!

So if I try to open a .tg link to a Telegram group I want to join I get a message box asking me what application I want to open the link with. I want to change it from the current one and select Telegram as an app that I've installed from the Microsoft Store, but that doesn't appear on the list when you click browse because it's not a normally installed program in Windows. Is there a way to get access to apps installed through Microsoft Store in order to set them as default apps to open certain links/file extensions through Firefox?

Hi, I'm trying to find out what's causing this behavior. My firefox sometimes, specifically when opening a second tab (doesn't happen on a third, fourth, fifth, etc. tab) and pressing F (like starting to type Facebook), makes my entire screen to fade to black for 1 second, and then comes back. If I do type facebook, it shows "acebook", ignoring the F entirely. It doesn't seem like a crash, it seems a lot like a functionality of sorts that's acting up, because it doesn't go black just like that, it fades. And it always takes the same amount of time with that fade.

What's worse, it doesn't always happen. If it happens once I can replicate it and keep doing it, but as I use the browser and it stops doing it, I can't do it again. Until, well, it does.

This is the weirdest thing. How does firefox control my entire screen like that? What's it doing? What instruction on my keyboard is F sending to firefox?

I haven't found anything like this happening to anyone online.

Any help please?

I really try to find an answer online but looks like nobody find this to be an issue. Of course i have my password vault locked with a master password. But remembered logins on websites like Google and Facebook are secured by cookie login. Which not require my master password. So when someone use my computer unsolicited, this person gets instant access to my GMail/Facebook.

So how to protect per-logged in pages without resetting cookie data? Because i liked to benefit from instant access to al those website so i don't have to login everywhere any moment i start Firefox.

Hi, How do I install Firefox Lockwise for Windows 10? I visited Firefox Lockwise's website (https://www.mozilla.org/en-US/firefox/lockwise/) and there's only installations for Android & iOS devices but I only want it installed in Windows 10. How should I go about it?

Waiting for your reply asap, thank you.

Cool Regards, Pallas

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:86.0) Gecko/20100101 Firefox/86.0

Steps to reproduce: 1.Opening bookmark by command-shift-o 2.Dragging boundary line of bookmark column (name, url, added date...) to resize the width

Expected results: The width of column is changed

Actual results: The width doesn't changed properly. The column next to dragged one is changed or completely ignores change at all.

Dear Community,

I have problem with my Firefox version 86.0 (64-bit). I have Windows 10 20H2 64-bit operating system. Firefox can't load some websites. For example I can load https://allegro.pl/ but I have problem sometimes with this website: https://allegro.pl/myaccount/newpayments_incoming.php

If you go there and use F5 key on keyboard (refresh website) sometimes this can't load. On other browser I don't have this issue. This very frustrated me because I can't work. On Windows 10 1909 on older machine (another computer) I don't have this issue with my firefox (this sam 86.0 version). So this is probably problem only with Windows 10 20H2.

Steps to reproduce:

1) Open new tab and go here: https://allegro.pl/myaccount/newpayments_incoming.php 2) Log in to your account for Allegro website (without account you can't load website) 3) When website loads normally you must refresh this website (F5 key on keyboard) few times (you must be patient, sometimes this can take some time) 4) When website can't load or it's load partly you can see that this stops loading when it try connect to analytics.google.com so I think that it is very strange behavior.

On other browsers on Windows 10 20H2 version this website works without issue. Only with Firefox I have a problem. On Windows 10 1909 version on another machine I can't notice this issue. Also on Ubuntu I don't have any problems with this website with firefox.

Can you fix it? I can't work on my computer with Windows 10 20H2 system. I musted to switch to another browsers (Google Chrome, Microsoft Edge). I contacted with owner of the website but this is not the first problem with Firefox on Windows 10 20H2 so you should fix it. I remember that I had some similar problems on another websites but I don't remember what was address for these websites.

Actual results:

Sometimes I can't load this website on Windows 10 20H2 64-bit: https://allegro.pl/myaccount/newpayments_incoming.php

When website can't load or it's load in a part you can see in the bottom of the browser that this stops when it try connect to analytics.google.com so it is very strange behavior.

This can be not problem only with this website.

Expected results:

I should load this website always: https://allegro.pl/myaccount/newpayments_incoming.php

I hope that you can fix it.

My Firefox version is 86.0 on Mac. OS Version is 11.2.2 Big Sur.

I found that basically all color rendered in Firefox is more vibrant than Safari and Chrome, maybe Firefox doesn't handles color management right and renders sRGB in full P3 color space, lead to a over saturate color for almost every element on webpage.

Hopes firefox can fix this soon, I love the efficiency and privacy features on Firefox, This is the only bit I found a little uncomfortable.

You can test your browser here: https://cameratico.com/tools/web-browser-color-management-test/ if you have a P3 support Mac or Windows.

Suddenly Outlook has added two columns to the left hand pane.

Is it possible to get rid of them as they just clutter up the page?

I have attached a screenshot and hope it comes out.

Thank you for your help.....Anthony

When I use Gmail in my up-to-date Firefox under Windows 10 or Linux and type e.g. "Leser und Leserinnen", then exit the draft and reopen it, "und Leserinnen" is gone. This happens to all tested feminine forms ending with "-innen", even irregular or non-existing ones, if they follow the masculine form and " und " (both preceded and followed by exactly one space). The truncation is case insensitive, and when I type the feminine form first, "innen" will be cut, and " und [masculine]" as well. Turning off auto-correction didn't help. Also, when I send a mail containing such a double form, it arrives correctly, but in my sent mails " und [feminine]" is gone. However, when I then open "forward" or "reply" with repetition of the sent mail, the deleted words are back in place. None of this happens when I use another browser or an E-Mail client or the Gmail app on my phone, nor does it happen with other mail providers, not even when using Firefox. I know this sounds weird, as if there were an automatic "politically incorrect maker". But it is exactly what happens. I wonder if anyone can replicate the phenomenon or - even better, find out why it occurs.
