Firefox 技術支援討論區

Hi everyone, When i go to the website config.office.com in firefox there is just a white screen. Nothing more. Instantly white. I have checked if this is an issue at the side of Microsoft but it doesn't look like it is. The website does load correctly in Microsoft Edge.

I tried the following in Firefox: - Firefox is up to date (Version 115.0.2 64 Bits) , I have had this issue in other versions of Firefox too. It's not a new issue in this newest version. - Tried disabling all the security features in Firefox, disabling all add-ons, and disabling the extra security for cookies - Starting firefox in safe mode (Shift click on firefox, then open the website) - Checked the Network inspector. All packets have status 200 (See the first screenshot)

You can check the second screenshot for the white page.

Some help is appreciated :) Thanks!

Here is a sample URL that works on Microsoft Edge (current version) and receives an error message on Firefox (115.0.2): https://www.t-mobile.com/home-internet The error received from the web site when using FF is:

Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

FF was working with all T-Mobile pages a few months ago and now fails with this same error on most pages.

To test on Edge, I pasted the identical address that failed in FF into Edge and it worked fine so I am confident I am comparing the same web page on the two browsers.

Thanks for your help. Claude

I subscribe to The Times (UK) and use many of their different portals. I am, however, experiencing a really odd problem. For the last three Mondays in a row when I hover over a link it shows one destination which is now three weeks out of date and downloads same when clicked. When I Inspect(Q) the relevant bit of script it shows the correct page for the current week. All other links from the current edition work as expected. The link works correctly on other days of the week. The IT support at The Times have no idea why this is happening and have simply asked me to do stupid things like clearing all cache and cookies relevant to their site. this has no effect whatsoever!

How can this happen and have you any help on the subject?

Hello, I recently installed a fresh FF 115.0.2 (after years of importing my old profile). I noticed a really nice feature, when double clicking a word, a search bubble would open with 4 icons (google, google maps, wikipedia and something else) and you could click one of them and it would open a new tab and search for the selected text.

Today I noticed it is missed. I didn't upgrade FF, I didn't install any new add-on and I didn't even close FF since the last time it worked.

Any ideas how to get it back? And how to add other providers to this very nice feature?

Thanks

Somehow this en.softonic nonsense has made it into my windows notifications tab under 'firefox' notifications. How can I get rid of it? I can't find it in the General, Add-on or Extensions settings of Firefox or Windows Uninstall to turn it off or remove it.

How can I get rid of it? I don't want it.

Thanks

Well done Firefox team.

I got a notification this morning telling me I could update Firefox to the latest version and I had nothing urgent so I did.

Imagine my suprise when all my bookmarks, my passwords and logins appeared to have disappeared. Well, not just "appeared", since I can't find them anywhere on my machine right now.

I've been using Sync for years and when I finally managed to connect (because apparently the password I had been using was wrong ? But did FF tell me ? No ...), I discovered nothing had been saved. Ever.

A really nice morning.

I have tried syncing to the time server and manually updating the time with no success. It is only happening on this computer. My other laptop and my Android are fine, so it has something to do with something on this PC. I've tried to disable vpns but that hasn't helped. Any insight is greatly appreciated since the timestamp is crucial for much of what I do!

hi, something happened to my themes. i can no longer see the preview/thumbnail of them, also the authors link is gone. i've been trying everything for hours, but couldn't find anything in about:config that worked. any help would be great, thanks!

So, whenever I open Firefox it will act normally and then after a second close by itself and when I reopen it, it will be in remote mode. I know how to fix this via about:config and do this every time, but I would much prefer a permanent fix, nothing else on Firefox or my computer indicates something else is going on, its just this. I've even at one point uninstalled and reinstalled Firefox and it didn't help.
