Firefox Support Forum

My internet has 750mb of bandwidth. Updated 64bit Firefox can only provide 320mb. I installed Chrome and the internet went to 800mb. What could be slowing down internet speed in Firefox? I restored Firefox, restarting everything. I did the same with Windows 10. I restored it to an earlier date. It didn't improve anything. What to do ?

When I start FireFox most times the browser comes up then stops and restarts with a pink color on the web address line. I have tried making changes in settings but I can not find a setting for this. If I restart Firefox right after this happens, I cn search or browse without the Pink address line. Why is this happening. It would be nice if FireFox technicians would respond to help questions instead of sending questions to a forem...

I have been using firefox for years. My current version is 126.0.1 (64 bit). Within the last couple of months(?) I am unable to reach a website that I use on a semi-regular basis axisgis.com/AshbyMA The problem exists on 3 different devices, an HP laptop running win 10, an older desktop running win 10, and an older mac desktop running Catalina 10.15.7 which apple says is up to date. If I use Safari on the mac the website works perfectly. If I use private browsing on the laptop the website works perfectly. If I use private browsing on the desktop the website works perfectly. On the laptop I ran the firefox in troubleshoot mode and the website still would not work. I cleared the cache on the laptop and the website still won't work. Since the problem occurs on 3 different devices that are not synced to each other I can't believe it is a cookie problem. Rebooting devices makes no difference. I rebooted the Comcast modem and the house router, no change.

Any ideas would be welcome.

Thanks, mike

J'ai reçu une notification de Mozilla/firefox me demandant de fournir des autorisations supplémentaires pour les extensions McAfee® WebAdvisor. La notification indique que si je n'autorise pas les mises à jour, je devrai supprimer McAfee. S'agit-il d'une escroquerie ou d'une tentative de vol de données ? Je vous remercie.

When I start Firefox it appears in a small window and it takes several tries to maximize it. In the past I right clicked on the Icon and I had a choice of setting the window to open in Maximum, this doesn't seem available now. How do I get the window to open in maximum on startup?

I have recently been getting an error message when I open Firefox saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". This has been happening since I clicked on a mail in Mail to unsubscribe from a spam/phishing mail list, which seemed to result in me installing Firefox Private Browsing, which I had never subscribed to. I have tried uninstalling Private Browsing but there is no way of doing that. I have even uninstalled and then re-installed Firefox completely but I still have the same problem. Because of the problem I have now lost all my bookmarks and history, and am unable to create new bookmarks and history. I have been on the help forums and seen that I can Disable Private Browsing by going through my anti-virus (Avast), which I have not yet tried because what I would really like to achieve is uninstalling and not having Private Browsing on my Start menu, rather than simply disabling it. Anyway, would disabling it solve the bookmarks and history problem ? Can anyone give me the solution ? Thanks. As you may gather, I am not very techno so you would have to give me the idiot's version of any instructions or advice.

Hello! I installed Firefox about a year ago, and for the entire duration it seems about 60% of the time the default fonts on various websites look weird (bold?). I have tried uninstalling/reinstalling Firefox, clearing the cache, etc. See attached images for examples. Help!

Hi need to get my old firefox back before installation of new version.

I have a subscription that allows for downloading of videos using a "DOWNLOAD" button that has disappeared after new version of firefox was loaded. also my antivirus application has disappeared. How do i put everything back the way it was. I'm using windows 10.

Please help

It was working fine and now the past few days I can no longer login to my Fastmail.com account other than from my Windows 7 pc

So no one including Firefox can email me

I am trying to email a link from chatgpt to my yahoo email account. When I try to open the link I receive the error 500 internal server message. I have emailed links from chatgpt many times before with no problem. Can you advise.

Thank you Barbara Krausher

Why do I need a new profile every single little update? How can I get my saved session, bookmarks, history, open tabs, extensions and preferences from my old profile? Manually copying files from the old profile is not a solution - it's a workaround and not a great one. Lots of things get left behind. Alternatively: what file in my "old" profile do I need to manipulate to trick Firefox into using it with the new version?

When I open Firefox, it is only a quarter of the browser in the right-upper quarter of the screen. How can I make it so the browser opens fully in the entire screen.

Hi,

The Lower Toolbar is quite handy, with for example Roboform.

Unfortunately, the way it's implemented, it comes above the lower part of the browser window, instead of being inserted at the bottom while the browser windows height is reduced.

That hides the search box when you type Control-F.

It would be nice if this could be addressed in a future release. I am using Firefox Developer 127.0b2.

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

Hello, I have a very weak internet connection and I've been experimenting with ways to lessen the burden of the slow connection by increasing the time that the cache from websites can stay on my computer (I've already increased browser.cache.disk.capacity and set browser.cache.check_doc_frequency to 2, but the files still end up expiring eventually forcing them to be re-downloaded even though I know these cache files never change).

So far I've had some success with this extension (https://addons.mozilla.org/en-US/firefox/addon/cache-longer/) it definitely works but very inconsistently so I've tried to directly edit the cache files found in Profiles\someprofile.default-release\cache2\entries but every time I edit the max-age on the cache-control line or any other line firefox just erases the cache file completely then re-downloads it.

TL;DR - Is there someway of getting firefox to ignore the cache file expiry dates and cache-control age or at least editing these files to extend their life?

I appreciate any help in this!
