Firefox 技術支援討論區

Firefox has begun opening in compact view. When I click to expand the view, it just moves the compact view to another location on the screen. I would like it to open in expanded view like it used to, but I cannot find anything under Settings or on the Help page.

I have a MacBook Pro and an Epson ET-3850 printer. I can not get my printer to do two sided printing using firefox but it does work if I use Safari. How can I get two sided printing using firefox?

Thanks ... Jan

Firefox keeps loading incorrect webpages for two websites. The websites are; https://www.diy.com https://www.trade-point.com The two websites work fine with Microsoft Edge but not with Firefox. See attached images. Please advise how to resolve this issue. Thnak you, Mark

As of recent I've been having troubles with my Firefox browser. Out of nowhere it has started relentlessly purging my browser history to the point where nothing lasts more than a week now before getting deleted, and it is only getting worse. Prior to this Firefox would save data from over a year and simply just remove the oldest data in order to make room for the newest whenever necessary. That is no longer the case now.

I'm fairly certain that I haven't done anything to cause Firefox to do this, but I can't be sure. Looked in the settings and can't see anything that would cause this.

So my questions are: 1.) Can the history deleted be recovered? and 2.) Is it possible to get Firefox to stop purging my history on it's own so frequently?

Any and all help is appreciated.

As an example: suppose you have 100 tabs open. Does Firefox use more memory if 50 are open in 1 window and 50 in another or if all are open in just 1 window? Does it make any difference?

I recently replaced most of my Firefox Homepage Site Icons with custom icons. (No easy task... loking at you Mozilla)... :)

Now that I have them replaced, whenever I start Firefox the custom site icons take a long time to load.

The previous default site icons appeared to be cached and I was hoping I could force my custom site icons to cache locally to improve loading times.

How do I recover my previous version of Firefox which I accidentally signed out of while signing on to a zoom session? I got a completely different version when I signed in again. I need my private details from the previous browser.

I can't save an image with an asterisk in the filename when saving from my Firefox browser. I used to be able to, but now any asterisk I add to the filename just vanishes like I didn't type it at all. I can change the file name in other ways, like adding words. I can still save from Chrome, so it's a Firefox issue, and a recent update. Help!!!

This all started when I got an email that was captioned: New sign in to Firefox Monitor.

Looking around I noticed that Firefox thought I was using Windows 10 instead of 11.

I am currently using a Yahoo Mail account and have been for years but recently when on the yahoo mail page I get a red notification tellimg me I'm not connected to the internet on the tab displaying Yahoo Mail.

All other open tabs are able to access the net with no problem.

The only way to clear the issue is to open task manager, select all user info whereupon I will see one or two entries under Firefox using massive amounts of memory, i.e most open windows will have between 4.000k and 10.000k allocated but the top two entries arranged under memory use will both be firefox showing around 13.000.000k and 1.500.000k but with no information to identify which tab in firefox is using that amount.

If you select the 13.000.000 and end process, it ends that entry and nothing happens, if you then end the 1.500.000 process it crashes firefox and every single tab and window closes.

Restart firefox and it will open with the session restore page, hit restore existing session and watch the pages reopen and one iteration will head for the 13.000.000 mark again and Yahoo will not load at all.

It usually takes one or two more crashes until the session restores and Yahoo Mail loads and opens as if nothing has happened.

Today however after 4 attempts I eventually got a cannot find server notice on the yahoo page so I hard reset my router and after manually diabling and re enabling my network adapter my computer re-established a newtwork connection but when I restarted Firefox again the restore session was greyed out and only the new session button was available.

In the new session it loaded Yahoo mail immediately and when I tried to see if I could manually restore the session using the top right menu button, there is no session restore information or button at all.

Go to the history tab and there are no closed tabs or windows ( both greyed out) but the recent history display and the history itself is showing all the previousl pages.

I searched online and found this link https://support.mozilla.org/en-US/questions/1267353#:~:text=If%20your%20tabs%20disappeared%20and%20the%20previous%20session,3.%20Close%20Firefox%20Delete%20sessionstore.jsonlz4%20file%20More%20items but none of the information in it matches anything in my file system even though I too am still using Windows 7. This is the version in the update history Firefox 108.0.2 (20230104165113) Details Installed on: 6 January 2023 at 15:40:33 Status: The Update was successfully installed

Can anyone help with the why one particular tab in firefox keeps trying to monopolise memory use for itself and how to stop it, and whether there is any way to recover the previous session information as I can't find anythig remotely relating to it on my system at all:-(

Thanks

I wish to cancel my Relay subscription, but I see no way to do so. There are a number of descriptions of how to do this on the Firefox web site, but they are ALL WRONG or INACCURATE. This should be dead easy to do without having to send an email to "support" (such as it is) or "the community".

My computer was factory reset and I had to re-download firefox. My saved passwords were no longer available after signing back into firefox. Before the restart, I determined I should ensure I had the most recent pw to log back in after the reset. I was able to log back in, but all bookmarks and pw's are no longer available. I can see the previous session when I log into the account. How do I retrieve those lost bookmarks and pw's?

We tried several times to log in to chase.com and repeatedly received this message:

****************************************************************************

An error occurred during a connection to secure09ea.chase.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

This is unacceptable. We do not want to use insecure browsers, and the Chase website was fine until the latest Firefox update.

When going to retiree.uhc.com/TRB and attempting to sign in to my account with username and password I am greeted with a message that reads "Something went wrong. Please refresh your browser and try again". This is not happening when using a different browser such as Google Chrome. Can you explain why Firefox is not allowing me to access my account on this website and tell me what I can do to correct the problem? Thank you.

I'm facing the problem of insecure when using caching on Firefox It's normal when tracking protection is turned off But we can't ask users to turn it off every time they go to our website const newCache = await caches.open('new-cache'); I can't open cache by this method
