It's very tricky the clone a FF profile, so I want to avoid that. (If there is a SIMPLE way to clone a FF profile, that would suffice. I have found no such animal.)

I would like to start Firefox by invoking different UserChrome.CSS files.

Is that possible?

I am not intereted in RUNNING both these simultaneously.

yes, I realize I could go through renaming and unrenaming files before starting FF to achieve this. But, I am I'm looking for a method using native FF resources.

I was trying to reset my password and was having difficulty and finally I was able to change. I also have been trying to delete VPN and have been unable to find how to accomplish it.

There is much more to the following that I received from ChatGPT: The first place to seek answers is obviously with VeePN. I asked ChatGPT the following questions, and as a result, I also have some questions for Firefox. Where can I get answers? I do not like the Edge browser for several reasons. Firefox, as far as I am concerned, is the best browser for my use. Due to the fact I reside in Kaliningrad I must use a VPN to access sites I used to take for granted when I lived in the Czech Republic. This morning, as usual, I tried getting connected to VeePN in my Firefox browser. As usual, it does one of the following: 1) “Something went wrong at our end.” & “try to update” or “contact us for assistance.” 2) Continuously refuses to connect, leaving with the message: “Connection Error. Can’t fetch server config.” 3) Connects very soon after opening Firefox, perhaps 5% of the time I try connecting to VeePN. This morning, I spent many attempts over the course of 2+ hours, and no connection. Sometimes I had to refresh the VeePN extension due to the immediate, continuous, fast popups of “Connection Error. Can’t fetch server config.” Then suddenly, without rhyme or reason, VeePN connected. Also, this morning I decided to test using VeePN on my Edge browser, and it immediately connected, with no hesitation. This begs the question. Is there something about Firefox that may be causing the issue? I have not changed any settings anywhere regarding WiFi or Network & Internet Settings. In addition, sometimes, when I tire of trying to get VeePN to connect in Firefox after decades of connection attempts, I will use my Browsec VPN. I have learned not to use two VPNs simultaneously, one or the other, not both. Also, it is worth mentioning that VeePN is far superior to Browsec, but that is my opinion based on how they both perform after being connected for a good period of time. I can be connected via VeePN all day and have no issues. Browsec requires regular refreshing. Either VPN, however, is affected by the internet connection and the wireless connection between my router and the dongle that sits on my desktop near my PC. Yes — based on what you described, this strongly suggests the problem is more related to Firefox itself (or the Firefox extension environment) than to your internet connection or VeePN service overall. I have added an image of all the Firefox Extensions I use, obviously, some in the list are turned off. I would like to add the information that ChatGPT provided, it is in a Word doc that can be uploaded to help if needed.

I would like to understand how DNS over HTTPS impacts browsing speed and privacy in Firefox.

Details: Hello everyone,

I am currently exploring Firefox privacy and network settings, especially DNS over HTTPS (DoH). I noticed that enabling this feature slightly changes website loading behavior on some networks.

I would like to ask:

Does DNS over HTTPS introduce additional latency? Are there performance differences between providers? Can corporate or public Wi-Fi networks interfere with DoH requests? Is there a recommended configuration for balancing privacy and performance?

I’m interested in both technical explanations and real-world experiences from Firefox users.

Thank you.

Server Not Found

Firefox can’t connect to the server at student.maharashtra.gov.in What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi.

This browser keeps doing this very annoying thing where it automatically pins recently visited commerce sites in a suggestions bar of a new tab's url. If I go delete the specific pinned page from my history, it will just grab a new page from the same website and pit that instead. For example, I recently visited chewy.com to purchase dog food. A page from Chewy became pinned in the dropdown for new tab urls. I deleted that page from my history. A different page from Chewy became pinned. This went on and on until I deleted *every single Chewy.com page from my history.* This is unwanted and frustrating behavior. Who does this help? I did my business on that website. I do not want to be told to go back and visit the site that wants my money. I know how to browse the internet. This is extremely annoying.

I use Firefox as my browser and have used Yahoo as my home page and browser for decades. Starting a few days ago, every time I type in the Yahoo search bar I get a Google search page result. I opened Bing and tried to search on their page and got the same result - Google. This is driving me crazy. I want my old Yahoo search back. I am at a loss as to how to fix this. I have looked at the Firefox settings and, of course, Yahoo is no longer listed. A shame. I don't know what to do at this point. Maybe the answer is to get rid of Firefox, but it has worked well for me for a long time. Any help will be appreciated. Thanks.

I am getting error 'Code: RCPTA:2' when trying to log into the Detroit Free Press (freep.com). I had never had this problem before but just performed a Firefox update and now have this error. It's like the Firefox update changed a setting related to Javascripts.

Na eBay slike proizvoda se otvaraju jako sporo i treba po nekoliko sekundi da se izoštre. Nekada je to radilo momentalno. Nedavno sam uspio naći riješenje ali se opet vratilo usporavanje.

Hallo,

ich habe regelmäßig das Problem, dass Firefox quasi meinen gesamten Rechner ausser gefecht setzt indem nahezu die gesamte CPU Leistung und der Arbeitsspeicher in Beschlag genommen werden. Ich surfe in der Regel mit sehr vielen Tabs. Ab ca. 100-150 Tabs benötigt Firefox bei mir zwischenzeitlich 10 GB Arbeitsspeicher und mehr und benutzt die CPU zu 80-90% sodass der Rechner teilweise kurzzeitig nicht mehr reagiert und einfriert. Besonders, wenn ich 100 Tabs und mehr auf einmal als Lesezeichen speichere (Tabs auch nur schließen, da der CPU Lüfter schon dauerhaft auf 100% läuft), friert der Rechner danach erstmal für 3-4 Minuten ein. Ich verstehe nicht, was Firefox die ganze Zeit im Hintergrund anstellt, während z.B. 250 Tabs geöffnet sind. Tabs vorzuladen macht bei der Anzahl keinen Sinn und die Wahrscheinlichkeit, dass man richtig voraussehen könnte, welchen Tab ich als nächste wieder aufrufe und dieser dann schon vorgeladen ist, ist eher gering. Gibt es Möglichkeiten z.B.: - den zur Zeit verwendeten Arbeitsspeicher sofort zu leeren, ohne einen Tab zu verlieren oder dass Firefox geschlossen wird? - dass es dann längert dauert, wenn ich einen Tab anklicke, da dieser ja nicht mehr im Cache ist, und erst wieder in den Arbeitsspeicher geladen werden muss, ist selbstverständlich und vollkommen in Ordnung. - Kann man irgendwo einstellen, wie viele Tabs z.B. im Hintergrund aktiv sein dürfen? - Kann man den zu verwendeten Arbeitsspeicher begrenzen? - und was passiert, wenn die Grenze erreicht wird? - Kann man irgendwo an den Zeiten oder ähnlichem schrauben, wonach Tabs automatisch entladen werden? Chrome friert Tabs scheinbar automatisch ein, zu mindest ist die performance dort besser.

Es bringt ja nichts, wenn alles versuche wird im RAM vorzuhalten, damit es sofort da ist, wenn der ganze Rechner damit in die Knie gezwungen wird und am Ende das gesamte System nicht mehr zu bedienen ist. Vor einigen Jahren ist Firefox bei zu vielen Tabs oft abgestürzt, dann hat sich schon gebessert.

Es fehlt mir an Einstellungen zur Anpassung, was Firefox im Hintergrund vorhalt und was Tabs machen dürfen, wenn sie nicht aktiv bedient bzw. benutzt werden. Manuelles "entladen" kommt für mich nicht in Frage, da es zu aufwändig ist, bei extremen "Multitabbing".

Ich bin seit meiner Kindeheit begeisterter Mozilla Fan (seit Gründung von Mozilla) und verteidige und empfehle Firefox wo ich nur kann. Aber dieses Performanceproblem besteht schon sehr lange, ist zwar über die letzten Jahre besser geworden, dennoch zwingt es mich schon fast, nach einer Alternative zu suchen.

Generell fehlen viele Funktionen für Extrem-Multi-Tab-Benutzer wie z.B., dass man Tabs in der Leiste markieren oder sortieren kann. Ein großer Segen wäre eine Funktion, dass Tabs, die man bereits als Lesezeichen gespeichert hat oder doppelt geöffnete Tab, direkt zu erkennen sind, ohne dass man den Tab aufruft. Aber andere Thema. Ich benutze auch keine vertikale Tableiste, nur die horizontale klassische Leiste oben am Bildschirmrand.

Ich wäre sehr Dankbar über Tips zur Lösung des Problem mit dem Arbeitsspeicher.

Grüße

Running Firefox 150.0.1 64 bit on win 10 Have down loaded Box, Thunderbird pro and dropbox but still flags non verification Have disabled antivirus etc and set xpinstall signatures to false but no change.

I have two desktop computers. both were fine. Now when I try to access a site i have gone to innumerable times it says "Blocked access". I can still get to the site on the other computer, but it is annoying to have to hop back & forth. I looked at the settings page, but I have no idea what I need to change to regain access.
