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?

Hi!

Where does FF store automatically downloaded updates on windows 10? Seems like last time this was asked was during XP time: https://support.mozilla.org/en-US/questions/751464 thus this answer is no longer valid. I am looking for win 10 version of this answer.

Hello! Since a month I have a strange problem - Firefox wont connect to any Google service - REcaptcha, google-analytics. Any site that uses these services would not load, or loads and waits until connection expires. I tried refreshing Firefox, the uninstalling and re-installing - the problem remains. I do not use any proxy or firewall on my computer. Opera and other browsers do not have this problem. Please, advice.

firefox moniter found my email in a new data breach february 4,2023. Firefox sent me an email about it. how do I know the firefox email is safe to click on highlighted items in the email?

I am facing recurring tab and window crashes on Firefox 108. This is one of the submitted crash reports https://crash-stats.mozilla.org/report/index/b930a34e-c41d-4514-9dbd-a09970230204#tab-details

I have tried disable extensions one by one but it does not seem to affect the problem. Or at least there isn't a clear pattern that can help isolate the problem.

How can I fix this? Can someone help me read these reports better?

A data breach happened in April 2019 which you reported to me today, 2/4/2023, but I have changed all passwords in the last month or so reported at risk, am I safe now that it is almost 4 years after that breach?

I don't know how to fix my issue. my banking page and roblox for my daughter have both been asking for codes. i enter the code and tell the web page to remember the device. i can log out 5 second and days later it doesn't remember the device. i not sure how to get it to remember my computer. i use firefox as the browser. computer not been moved internet has not been switch my ip address should be the same. i dont understand why these 2 pages cant remember my computer and the bank says i am the only person this is happening to. webroot is not active acount it a old softwear.

Firefox 109 is horrible and I am trying to revert to 108. I have the "Old Firefox Data" file, but have no idea how to get ALL that info back into 108. I am so very upset and frustrated right now! So much wasted time. I cannot believe Mozilla did this to us with no warning!!!!!!!! I have seen some articles on how to get the info back, but I don't really understand them. I am relatively computer-savvy, but I definitely do not understand how all this works. Some "Firefox for Dummies" at this point would be greatly appreciated. I am on a PC using Windows 10 professional 64-bit with automatic updates so it's current.

Hi Firefox community, I don't want to store any account login data (also not usernames) on the shared PC that I'm using. In settings > passwords there is no entry, and under access data and passwords any options are deactivated. Although passwords are not stored, Firefox shows the user names/account names whenever I click such field. Where can I deactivate that user names/account names are stored and shown? Many Thanks in advance. Best wishes!

Hi

I am finding it near impossible to use Firefox at the moment, I can no longer successfully log on to my First Direct page page, My Royal Mail OBA page, I couldn't get the Virgin media chat link to load from firefox the other day, this is just to name a few. I can do all these tasks on other browsers, just not on Firefox, I am at the point of totally giving up on using Firefox and unistalling it. I have tried clearing cookies and cache and it did nothing to resolve these issues.

I have no idea what is going on but I am finding that the list of websites that I can no longer use on firefox just grows and grows. Any advice?

I use firefox 108.0.2 (64-bit) and MacBook Air (Retina, 13-inch, 2020) on MacOS Monterey.

Thanks Louise

Hi, I recently began having trouble getting Youtube to work on Firefox.. Doesn't seem to want to connect, slow to open, mostly not at all, sometimes loads half the page....etc Constantly comes back with a message that I am not connected to the internet, which is nonsense.. It loads instantly in Microsoft Edge..which I normally don't use at all. I have deleted all history , Cache etc multiple times and that works maybe for one time and then the problem is back again.

Appreciate some help.

I installed Mozilla VPN just over one year ago. I never could get it working right (my issue I'm sure) and simply forgot about it. Until I was billed for another year recently. I really do not need VPN at all because I always use secure methods when online such as Kaspersky protected browsing and PayPal and Zelle also. Please direct me to whomever is able to cancel my VPN account and possibly issue a refund. A phone number would be nice if a better explanation is necessary. Thank you for helping me, I look forward to hearing back.

My bank delivers monthly statements as rasterized copies of their paper statements. They are clearly pixelated and not text. However, when I open one of these PDFs in Firefox I am able to select the rasterized text, as you can see from the attached screenshot clip.

How is this possible?
