Firefox 技術支援討論區

Hi there, I have been trying to get into a Government site that I have to use and I continually, only from today, get a message saying the Certificate is outdated. What can I do to override this issue? Cheers!

Why would Firefox browser version 100 run slower on my desktop than my laptop, same version and exactly the same settings. Both are connected via Ethernet connections with 500 mbps speed. The desktop has more memory and a faster CPU than the laptop. The browsing on my desktop lags much more than my laptop.

When I run Ookla speedtest, the laptop download is 310 mbps and upload is 363 mbps.

When I run it on the desktop the download is 118 mbps and upload is 96 mbps.

Any help with this is greatly appreciated.

Hello. I don't know which Firefox release broke this essential feature. The problem started after I enabled Aero in my Windows 7 system. It happens often if I have an open tab with https://www.o2tv.cz/ which uses some DRM to play TV content.

hi. firefox is my laptop was not connect to webcam. in this url

[https://www.html5rocks.com/en/tutoria.../intro/]

in (Apply effects , CSS Filters) part of page.

(when i click "Capture video" the LED near the webcam hole is on, but preview not shown.

but in chrome, edge and opera connect successfully. first LED on, then preview is shown with no bug!

(first i check firefox, not connected, then check in chrome connected, NOTE: device is not busy with chrome when i check firefox, i am a web developer:) )

please help me.

When I start typing URL's in Firefox, it will only ever suggest the URL so far as the top level domain. For instance, I frequently visit trakt.tv/dashboard. But when I type "tr" into the URL bar, Firefox only ever suggests trakt.tv - I have to manually press the forward arrow key and type in "/d" in order for it to autofill the rest. It doesn't matter how many time I type the full URL in or even the fact that I've deleted all history only visited trakt.tv/dashboard, Firefox will still only autofill trakt.tv

Is there some about:config setting I can change to make Firefox recognize and prioritize specific frequently visited URL's over just top level domains?

So weird, in the last few days, I've had intermittent behavior using FF.

Some examples - I log into my Gmail account, and it works for several minutes and then goes unresponsive and I can't get new mail, when I click the refresh icon or refresh the browser. - Last 3 days, when I click a hyperlink in an email, a new browser tab opens, but it's blank, the url doesn't seem to pass to the new tab - When I type a search term in browser address bar and hit enter, the tab refreshes but nothing happens... e.g. https://www.google.com/search?client=firefox-b-1-d&q=firefox

Troubleshooting steps tried. - Disabled all extensions - Started to uninstall FF, but got prompted to "refresh firefox" instead, which I did yesterday, but still have the same problems...

I can access Gmail and other functionality works fine on Chrome on same laptop. I've used different laptop with FF and it works fine, both machines on the same network....

upon enabling "do not connect to http" very, very, very often i got the attached error message when the site said it was https and it was very often reliable places like my bank and TaxAct. It seemed like such a good idea but i quit out of frustration.

After a reinstallation of FIREFOX, it failed to login to sync with Firefox. My account and password input are correct. And I can login to my accout with Chrome (https://accounts.firefox.com/).

my OS: ubuntu 18.04 firefox version: 100.0.2

Dear Mozilla Community members,

For a while now I get sort of an error message some time after Windows start (every time): "XULRunner Could not determine any profile running in backgroundtask mode!"

I managed to find out that XULRunner is connected to Mozilla but I haven't found any info about this particular message so far, therefore, I would appreciate your help solving this issue.

Thank you in advance.

Kind regards, Ewelina

Indigo Slate has created an interactive site for our client but on Firefox browsers on both Windows and Mac the interactive I i frames are non-responsive and often blurred out: https://exploresurface.com/#/en-us/touchscreen-display is one example of many on the site we have created. This issue does not occur with Chrome, Opera, or Microsoft Edge.

A recent update had destroyed my firefox experience.

Recently I've noticed that that this client no longer stores sessions. It will only store one session, the last session, and any stored sessions that are still stored when the client crashes again becomes corrupt. I used to rely on sessions to save large amounts of tabs. However, my client just crashed due to a power outage, I was quickly skimming through my tabs in order to reduce cpu usage and weed some out... when the client suddenly crashed again before I could restore them. I lost them all.

All of a sudden I find myself without an incentive to keep using firefox. Why have you made your client worse? Everything I had was gone, and due to an accident. There is nothing loaded on my computer. And yet it crashed for no reason and everything is gone. If I had an older version of firefox, this would not have happened.

Can you please tell me what happened to your restore session feature and why its total garbage now? Please fix it. I really hate losing weeks worth of research. And no, looking in my history wont help. I have reviewed thousands if not tens of thousands of websites over the several weeks it took to accumulate that research. Finding it all again in my history is impossible. That's why I rely on tab storing services.

How about you make a restore session library tab that stores all your stored sessions securely. I am tired of this data constantly being deleted.

Is it possible to use the keyboard only to adjust the width of the browser window? In other words, is there an alternative to clicking and dragging the mouse to change the browser size?

Thanks for your help!

in startpage of my ms account all ms apps can be opened...........EXCEPT the app Onedrive. What to do to make this work?????

using MS Edge all is doing well!!

thanks in advance

Hi I am trying to change the default homepage Firefox logo to my own, but i could find no tutorial on how to do that. I only found 7-9 year old posts, that did not work. So my question is: Is it possible to change the default firefox logo on the homepage to my own one, and if it is then how?

Firefox Google app Firefox for cell phones, Bookmarks you cannot press down and drag to bookmarks saved to put saved bookmarks in alphabetical saved order Otherwise as you save bookmarks it should save bookmarks alphabetically

Also saved add to favorate topics icon that appear on home page should be alphabetically saved or press and drag to saved already topics you have stored
