Firefox Community Forum

I cannot get into my online accounts, as I have always done for years. After I select the site, the screen looks like it is working, but then a new empty window pops up: the tab says "citi 400 Bad Request" At the top of the empty screen it says: Bad Request. Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I couldn't log into a site and it was suggested to 'clear cache' as follows: - settings - privacy and security - cookies and site data - clear browsing data BUT only cookies and temp cache sites. By mistake I believe I ticked browsing and download history too, and looks as though it is irrersible? Now I no longer automatically get all the little boxes I used to get for usual regular log ins (eg The Times, Meteo, banks, email etc) I think I can use 'add shortcuts' and re-enter these, but any other suggestions? With many thanks.

I have FireFox set up to reset every time I start a new session which causes DuckDuckGo's AI search to reset every time. Does anyone know how I can set it so it doesn't do that? It's annoying always having to disable to every time I open a new session.

Every time I select Gmail on Firefox page, it requires me to sign in with a code. I have selected 'Strict' for browser privacy and 'Clear history after closing Firefox'... plus a number of other settings. I then get a notice of someone signing into my account each time, as does the person who I use as a backup to my account. I'd like not to go through that each time I access my Gmail account.

Thanks for the help.

In Firefox, I have several windows open, each with many tabs. (And BTW, I love the Firefox tab-organization feature.) I would like to empty the cache and delete all cookies. Will that close the open tabs? Is there a way to delete the cookies, empty the cache and preserve all windows & tabs?

      Thank you!

As has been mentioned many times before I am sure, it would be really helpful to be able to have a less laborious way to add exceptions but as I have been through the ridiculous process of typing in site addresses manually one by one without having any sensible way to record these addresses already I guess it won't help me now. The ridiculous aspect came from having to take screen shots of the list of sites from the manage data list after deleting everything not wanted, scrolling down a windows worth at a time, copying that screen shot into multiple copies of a graphics program then shrinking each copy of the graphics program and Firefox so each can be seen so I can manually type each address across.

I know I am supposed to be nice but this is just insane. It is 2025. There is a thing called copy and paste. Apparently some people at Mozilla are not aware of this.

Having got that off my chest the next issue is that the deletion of cookies and data only occurs when Firefox is closed. Who closes Firefox? Why would you close Firefox? I currently have 24 tabs open. Why on earth would I want to close them down just so they have to be selected one at a time and reloaded? What is the thinking behind this stupidity?

The only time I close Firefox down is when Windows is restarted for updates (every application) or when IDM needs to update as I found this negates the need to restart Windows (Firefox only).

Other than those situations I am trying to work out how to fit this cookies/data deletion into the normal operation of my computer. There appears to be a lack of a suitable way to deal with this situation. Would it be considered acceptable to just wait for those times Firefox has to be closed? This would be far better than what I have been doing up to now but why wouldn't Firefox delete this data when the last tab for a site is closed? There are a huge number of sites I bring up due to searching for something and close them immediately or after reading what they have to say.

I have been using computers for about 30 years and have long lost the inclination and to be honest the ability to delve deep into them. Today I just want to have them do what I want/need without unnecessary complications.

Have I got this situation right or is there something I have missed? At the moment IDM has been having a lot of updates thanks to YouTube's greed but before that I found I generally only had to restart my computer for MS updates and when strange things started to happen.

Hi folks

I have a particularly infuriating problem. A few weeks back, Firefox stopped displaying my usernames and passwords whenever I wanted to log into a site. This coincided with my installing BitDefender, although I don't know why.

Through googling I eventually realised I could go into about:config to fix this. signon.rememberSignons displays as false, when I turn it to true it fixes the issue.

But here is the problem I can't solve. Everytime I restart firefox or my PC / Mac (I am using both, with a syncronised account on both windows and MacOS) it sets signon.rememberSignons to false AGAIN. Which means every single time I browse I have to go into about:config and fix this. Maddening.

Please can you help?

I am using Firefox (156.01) on a MacBook Pro (2023, M2 Mac Pro, Tahoe 26.7).

In Privacy and Security settings, I have checked the box to clear history and site data on closing. History is clearing, but site data is not. I can manually clear history and site data by going to the settings when I reopen it.

I noticed this issue about two weeks ago (not sure when it started). I have closed Firefox multiple times, restarted my computer multiple times, even updated my OS during this time, but the problem is consistent.

If I go to Clear Data for Specific Sites, I am also noticing that cache size is considerably higher than the sites listed (e.g., it might list 4 sites with a total of like 2MB but the cache size might be 30MB).

Do you have any suggestions for what might be happening and what fixes I might try?

I have one website that gives me a "Secure Connection Failed" If I click on the icon in the left address bar on mybrowser, I am given an option to "Clear cookies and site data" I click that and then appears a blue button at top that says "Clear" Now when I do a refresh of the tab, everything loads fine. This is Newsmax.com I read the news there. IS there a way to into Firefox settings and make an exception to https"//newsmax.com and make it so I don't have to keep clicking "Clear Site Data and Cookies" ? Thanks!

I saw a very confident by a 'support volunteer' that the interface contains controls to delete traces.

Show me in the in interface where these files can be deleted:

C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\0NB2KS6j.Profile 1\cache2\entries

C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\0NB2KS6j.Profile 1\safebrowsing

Some very bold claims that I don't see backed up by anything having to do with reality.

(Sorry if I wasted anyone's time. The issue turned out to be my large external monitor for one of my computers. When I was not using it, the smaller laptop screen did not allow all Firefox setting pop-up windows to display fully, so I could not see what I was used to seeing. When I connected it again to my large external monitor, everything was fine. That is why the other computer had no issues.

(So it had nothing to do with Firefox at all, and I am sorry if anyone read my question! Thanks.)

For the last three days or so I have been haivng problems with loggin in to sites. I no longer log in automatically to my many of the sites I use, particularly those set for my home page such as IMDB.com, ebay, web.whatsapp.com etc. Everytime I restart firefox I have to log in again. This started I think wit hthe latest update 155.0.1 (my current version) installed 5th sept 26 or 155.0 installed 3 sept 26

It doesn't seem to be reading the cookies that exist. I have it configure so all cookies are cleared on exit except those in the exception list, which are those for my home page plus about 30 others I log into. There is definitely cookie data there for these sites. I hve tried everythinig but this clearly seems to be a bug. at the moment I am using Opera since the necessity to keep loggin in to every site every time is just too much.
