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?

Hello there,

It's probably a simple one line of code solution, but I don't find the answer or how to do it.

I started yesterday writing add-on code for Firefox using javascript. I'll try to explain what I want to accomplish here.

There is a feature with the browser where we can drag and drop the website URL to the desktop to create a shortcut file that will open the website at the URL address. This works fine, but it can be tiring manual work.

I'm trying to accomplish the same result, but with code so that when I download a file with the add-on its URL shortcut is also automatically saved.

I searched enough to see at least one other add-on that seem to be able to save a URL as file, but there's a few problem. One is that the file does not contain the thumbnail like the original URL created from the browser itself. Another is that the file size takes 10 to 100 times more storage space. Lastly, when I open it Windows display a warning message that needs to be answered to continue. That extra step gives a bad experience. I admit that I haven't looked at the code yet, but I suspect that it won't do the result that I want even if I understand how it works which I'll take a chance to do.

Overall, I would say that I found nothing like the default drag and drop option.

I'm afraid that if I ask if is there such feature the answer will be negative.

Any help is welcome. Thanks.

Hi! I've been using Firefox the last 8 years, and so far I have not had any problems. I have latest version of Mac OS. I used to play Friv flash games at https://www.friv.com/, but it has not been updated for a long time, so I started playing at https://www.friv5online.com/, https://www.desura.com/ and https://www.y8games.center/. I don't remember exactly when it started, but definitely after the next update Mozilla and now I can not to play any game! When I go to the page with the game, there is a black background... See attach

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?

So I was on a theme spree trying to find something that fit my tastes better before deciding I would opt for the custom CSS Firefox route, however, I added Dolan's Dynamic theme (https://addons.mozilla.org/en-US/firefox/addon/dolans-dynamic-theme/) and when I tried testing it on other sites I came to realize it was not actually dynamic and decided to use a different theme. However, even after a complete browser refresh/clean-up, as well as a fresh installation of Firefox, my browser still reverts to the light / dynamic theme when I click out of the Add-Ons page. I will disable and remove all added themes and select the default and it will take effect on my browser, however when I ctrl+t or click new tab my browser reverts back to the light / dynamic theme.

Really upsetting seeing as I can't stand light themes and I prefer using Firefox for my web development work however now Firefox is sidelined for Chrome (which I cannot stand using). Any and all help or input will be appreciated and if I can provide anything else to help I will gladly do so.

Suddenly a week ago or so, Disqus comment boxes no longer appear. I reported it to a website that employs Disqus for commenting. They have been investigating for a couple of weeks with no response.

There was a question asked on this forum in 2013 that describes the Subject, but nothing since. Running on Window 10 Home.

This problem does not occur on my Windows 10 machine with Edge or Chrome browsers.

Nor does it occur on Ipad or Android browsers.

Thanks!

I'm not that tech savy. all I want to do is add print preview back to drop down menu, complete with sizing options, etc. many are unhappy it's gone as a default. can you tell me how to, simply, assume I'm an idiot, how to restore it?

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.

Greetings,

Today, I went to access my Bookmarks, & found them "Empty", other wise "Missing"!

I found the "How to recover missing Bookmarks" topics, & that did bring back,what I consider to be My "Permanent Books", bu the section called "Other Bookmarks" will not come back, no matter how many times I go through the "Restore Bookmarks".

I Absolutely need that section to be restored, for I had many files in that section that I updated daily, that I planned to move to the "Bookmarks Section".

How can I get get this section restored?

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.

I can not press the "Backspace" on YouTube using Firefox, but my keyboard works fine cause in Chrome and Edge it works perfectly, I've already refreshed the tab and still not working. Have any idea of what's going on?

Hi guys i'm new in the forum so i have no idea if anybody else allready had my problem,i've tried to fix it myself but i cant seem to get it done. Yesterday i had a problem with my OS linux,and i had to reinstall the system,while i was pretty sure i had all bookmarks saved in an external HD i went straight to a quick format and reinstall of the OS,after installed all the due system update.

The Problem:

While i was importing the bookmarks.html i stored in external HD i noticed that nothing was being added in the bookmarks of Firefox,so i tried few times just in case i was doing something wrong but still nothing was being added in the bookmarks,so i tried to import the bookmarks on Tor Browser and the same thing happened nothing was imported. So it came to my mind that the .html file could've been damaged. Now i tried many ways to open the file either in command line or text editor i even tried using libreoffice,in the case of text editor,command line such gedit,pico,nano it loaded the file but it was heavily encrypted,in the case of libreoffice shortly after i tried to open the file popped up a message telling me that the file was corrupted and libreoffice couldn't read it and stopped.

I need a solution to either fix the .html file or decrypt it so i can recover the web addresses inside and it would be very bad for me since my bookmarks.html is 3.3Mb large with ALOT of bookmarks inside.

Can anybody tell me how to?

Thank you in advance for any help or suggestion that may help me to retrieve my bookmarks. Ludo.

P.S. OS Linux BackBox 7 up to date along with it latest version of Firefox that update server provides me.

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.
