Firefox 技術支援討論區

Hi,

Since upgrading to FF100, almost all of the 'select' boxes on my webpages have white text on a white (or very light) background, and are only visible when hovered over, see attached screenshot.

How can I rectify this please?

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

Hi New Dell Inspiron 15-3000, installed Firefox 100 in new laptop, transfered all files via LAN from old laptop All websites work ok except 2 of the 4 banking websites I use. One site will not accept my login the other will open after putting in my login twice Have gone to "troubleshoot mode" and both sites work , go back to "normal" and they do not work Any clues how to fix this, not to technical please I am not a computer whizz and all children have left home Many thanks Ron Managh

Hi, yesterday I got a new computer and I installed the Firefox on it, but when I started the browser for the first time, it was a mistake (I pushed the button by accident), so I immediately closed it. It was asking something about allowing the use of coolkies, but I didn't answer to that and simply closed the window.

The thing is that since then my firefox don't load properly. The buttons and the autocomplete are normally responding, but all pages (including the settings) are blank and sometimes it won't start at all and I have to close it with taskmanager to make it open next time (but still blank).

Does anyone have the idea what's going on?

Thank you.

Hello Everyone,

After inserting the proxy information, webpages in the container tab refuse to load/connect, I insert the IP address and I've also tried the Fully qualified domain name, using the type://host:port syntax, I get "The proxy server is refusing connections" and "The connection has timed out" error messages.

If I setup the proxy via the settings menu the entire browser uses the proxy server address, I am trying to specify a different proxy server for each container.

Using Windows 11 and want to set Gmail as my mailto option when clicking on email links on websites. Under Firefox/Settings/Mailto I no longer see the option for Gmail, not an expert on technical matters so I have googled the problem but still can't find a solution. Do I need to find an App on Windows or perhaps an Extension within Firefox, feeling completely lost at the moment.

Is there any way (as in Thunderbird, via layouts.css.devPixelsperPx) to enlarge everything on a given monitor/display/colorDepth setting? Or an approach using userChrome.css that impacts everything, not just displayed text in the browser. Yes, this is a "tired old eyes" (excessive nanoseconds spent looking at bigger and bigger displays with higher and higher resolution) type question. My setup is multiple boot OS including Windows 11, Ubuntu, Manjaro, Arch. In each Firefox is the default browser, but Chrome and Edge seem to have more fine-grained controls for managing the chrome display than Mozilla. Using the latest 64-bit Firefox (100.02) if that's helpful.

Hi,

There are two suggestions (or questions if I simply cannot find these): - as the default behaviour of the browser, I want to be able to only see websites from Europe. Somewhere on the net I found that the following address does it: https://www.google.com/webhp?cr=countryAT|countryBE|countryBG|countryHR|countryCY|countryCZ|countryDK|countryEE|countryFI|countryFR|countryDE|countryGR|countryHU|countryIE|countryIT|countryLV|countryLT|countryLU|countryMT|countryNL|countryPL|countryPT|countryRO|countrySK|countrySI|countryES|countrySE

However, when I am trying to use it in firefox as my Start Page, it opens all of these in separate tabs and it does not work. Also as far as I understand using the link is not possible for new tabs.

The reason is simple. For example, when looking for cooking recipes, pages from the USA use strange units that cannot be understood and there is no point in translating each of these manually as all recipes are available in million of versions - it is just a matter of clicks. But I don't want to waste time each time on checking the websites one by one; if the cooking website is from Europe, the units will be of a standard and I don't have to worry. It is the same in relation to many products of any kind. European and American markets are completely different and reading description of something only to find out at the end that it is only available in the USA is waste of time.

- it should be possible in firefox to block some websites or portals by some button. I know that there is an add-on for this but it is only for 10 pages or so, so in reality it is not very useful. It also only works in the way that the page won't open when clicked on. However, it would be much better if unwanted portals or websites were simply removed from search results.

There are too many fake websites nowadays providing incorrect or misleading information. If it happens that I come across one of these, I want to be doing that only once - and block them forever.

Hi everyone,

I would like to change the order of Search Bar suggestions, if possible, because I find the "Firefox Suggest" section's results more relevant to what I usually look for.

Specifically, as shown in the image I attach, when I type, I get some suggestions, and then I can see the "Firefox Suggest" section. Is it possible to change the order and place it above the suggestions?

Thank you!

I am trying to open one of my bookmarks and it sits and spins for a long time then a message comes up that I am running an outdated browser and it needs to be updated to support their site.  ??? But I think I have the latest update.

In Firefox, my instructor and student grade sheet no longer displays the horizontal scroll bar to bring more data extended off to the right of the page into view. I have an image attached where the scroll bar should be present. This begin in May sometime, and I'm not sure how to fix. I have tried re-installing fresh a few times, and removed any custom settings that might have been in place. Any and all help would be VERY appreciated as one of colleagues is super frustrated and I would love to find out an answer for both him and myself.

I have tried numerous times to copy over the contents of my Firefox default profile folder from a Windows 10 PC to a new Windows 11 PC. I followed all the instructions as far as I know (when either saving or pasting the folder contents, Firefox is off; successfully downloaded and installed Firefox on new PC creating a new default profile which is where I pasted the contents from previous PC's profile, etc.) When Firefox is restarted on the new PC, it is just the same as the new installation -- no bookmarks from the old profile show up, e.g.).

Any ideas for how to get this to work are greatly appreciated. I have a lot of bookmarks and need to be able to access them on new PC. (BTW, this approach worked just fine when I installed a new disk drive on the old PC about 5 years ago and brought all the Firefox profile data over - everything came over as expected. I wouldn't think the fact that this is a Windows 10 to Windows 11 porting has anything to do with it not working -- these are just profile folders.)

Would Synching the two PCs work better? Does Synch just add all the profile and password data on the two PCs together so that each ends up with the total of what was on the two individual PCs and nothing on either is lost? When I looked at Synch on new PC, it was not clear how to get it to point to the old PC - Add a New Device just seemed to point to a phone. Again, any help is much appreciated.

When I log in to survey websites (e-rewards or one opinion), they get the neverending clock so I can't choose & take a survey. I get into the website & can do everything except for taking the survey. Works fine in Edge.

My HP Omen has 2 hard drives. Originally, Firefox was installed on the C: drive and working perfectly. In order to clear up space, I tried to use the Windows Move feature to move the program from the C: drive to the secondary (and larger) E: drive. Since then, Firefox won't work aside from opening a Firefox window. It will load no pages, settings, etc.

I've tried uninstalling Firefox from both the C: and E: drives. Searched for any remaining files and deleted them. Deleted Old Firefox Data folders. I've reinstalled Firefox, without the option of where to install it, but it still fails to work at all. I get an error message regarding a missing file, VCRUNTIME140_1.dll. I've searched for the file and it's NOT missing. It is in both the Firefox folder and the Windows/Systems32 folder.

I've searched for data in the Users folders that might relate to Firefox but NOTHING seems to work that will allow Firefox to work again. I've tried putting Firefox in Troubleshooting Mode but it won't restart as it says it needs to. It just won't work!

If anyone can just tell me how to COMPLETELY remove Firefox from both hard drives so that I can just do a clean, new Firefox install, that would be preferable. I know how to import bookmarks from Chrome.

If anyone can offer some help for someone who isn't great with computers, I would greatly appreciate it. If you need any other information, please don't hesitate to ask.

Following direction on Help Page - Trying to sync tabs, bookmarks etc from one laptop to another. In settings, devices are said to be logged in and sync set to sync pretty much everything. Clicking the menu top right - only shows my email @ the top, then New Tab etc - but nothing about "Sync Now" or "Sign In" What am I missing? TIA, Jean

At work with work with test servers. Sometimes those are using just HTTP, sometimes HTTPS protocol. However, once Firefox sees HTTPS, it does not let to go back to HTTP protocol.

Not sure, why a browser should know better than a user (when typed the whole URL, including HTTP://) to use HTTPS. Also, when the error page ("Unable to connect") comes, there is no option to use HTTP instead.

Why on the address bar, when either Delete key or right-click-delete are used the autofil for that host / domain are not cleared? Why that error page doesn't have a well described (warning the user of the consequences) option to still use HTTP?

Been using Firefox for long time on a Win10 machine. Motherboard failed. Saved the C drive. Question is how to move bookmarks (profile files ?) from the old C drive to the new Win11 computer? I tried moving the profiles over from the old C drive to the new computer but Firefox would not recognize them and shutdown. Restored the Win11 files and Firefox is again happy.

My site that uses Twitch.tv iframes no longer works because the Twitch iframes are unable to access their own cookies. When attempting to take any actions in the iframes, they ask to log in, and when the login flow is completed, nothing changes, it continues to not have the login state transfer over to the iframe. I'm hoping this is unintentional as it breaks entire use cases of iframes. I have no need to access the cookies myself, just let the site that is being frames access its own cookies!! This is WITHOUT the new protections that are in testing right now, but those ALSO were breaking it. Now it is broken even with them turned off. I will be using Edge for the foreseeable future until this is fixed I suppose... Love Mozilla and privacy but this is broken, sorry.

Getting error SSL_ERROR_BAD_CERT_DOMAIN on all my sites that are signed with a SSL Cert from my internal CA since updating past version 99

This appears to be a bug starting after Firefox version 99 on Windows because after i upgraded to Firefox version 100 i started getting this on all my SSL Certs from my CA and they worked fine prior to the update. Can anyone confirm if something changed after version 100 that is causing this?

Thank you.
