Firefox Community Forum

Been working with Last Pass support with this problem and it appears it is a Firefox problem not Last Pass. In the past when I closed my browser and then reopened it later, I had to enter my credentials to log into Last Pass, that all of sudden changed. Now when I open my browser, the credentials are automatically entered, exposing all of my credentials to someone who merely opens my browser. There are several items that lead to a Firefox problem: 1) I have Last Pass also on MS Edge, it acts correctly; 2) If I log out of Last Pass before closing Firefox, then when I reopen Firefox, I must enter my credentials to log into Last Pass. Firefox seems to be "remembering" the status of Last Pass when I close the browser, then reopen. We (myself and Last Pass support team) know all "boxes" that should be checked in Last Pass are and all that should not be checked are not. I even uninstalled Last Pass, no different. I went to uninstall Firefox, but was recommended to "Refresh" so I did, no help! Using Firefox ver. 149.0.2 (64 bit). I see this problem as a security issue, putting all of my credentials for all websites in jeopardy. At this time it seems my only solution is to change browsers to Edge or Chrome, however, I have been a Firefox fan since almost the beginning of Firefox and don't want to give it up--please help.

I can not log in to home depot website because it won't send me the verification code. No other website gives me this problem and I can log in with Chrome.

How can I fix this?

Using the Firefox browser: Logging into MS365 via https://login.microsoftonline.com has recently caused the “Copilot homepage” (m365.cloud.microsoft) to freeze. There is no response to mouse clicks or keyboard input. The login name is displayed in the bottom left corner, but there is no reaction with information and options as usual. The “Show App” option above the login is missing. Entering the username, even in MFA input, works without errors; all users are logged in via Entra. Access via MS Edge works as before, as does Firefox.

PR_END_OF_FILE_ERROR happens far too often (and with other well known sites too). it seems to happen more often since the 149 release.

I must assume that you are getting far too sensitive and don't care about real well known sites.

My problem may not be from the same cause, but I'm experiencing the same issue. Ever since my MacBook M3 Max updated to Tahoe, Firefox has been draining my battery incredibly fast. Before Tahoe, I could count on 8-9 hours of constant work with mixed use of higher processing work. Now, I'm lucky to get 4 hours of light browsing. Before I totally blame Apple, has anyone else experienced a recent shift?

from some dayes before does not work `www. bdris.gov.bd' site. another site work prperly. how can i get the system please, tell me that. thanks

I used to be able to highlight any non-English text, right click it, and choose "Translate Selection to English" to get a popup window with a translation. It would auto-detect the language I had highlighted and then give me the English translation.

As of a few days ago it only defaults to translating from English to Japanese. It no longer auto detects the language I've highlighted, and it no longer defaults to an English translation. I have to manually change the languages in the drop downs in the popup window each time.

Every help article I've found on google says I need to change language options in the settings, but they're all set to English. There's no mention of Japanese anywhere, yet Firefox insists that I want Japanese translations. My PC is also set to English.

Apparently sometimes it can still auto-detect the language since I just tried to make a screenshot and it was able to detect French -> Japanese, although many other times it thinks the Russian (or whatever) text I've highlighted is English.

Just letting you know after trying for a week to find a solution to this problem, I am leaving Firefox after 20+ years. I can not work from this platform any longer.

Hello, Windows 11 Firefox doesn't work with some sites e.g. - https://kanopy.com, https://my.echecks.com/..., cpb.bank and others. I have to switch to Chrome to visit those sites. I keep boosting of Mozilla and its products. I assist and try to teach other to use browsers, specifically Firefox. Then I have to direct them to Chrome because Firefox is not working with a specific site.

I can't see text using Dark Reader on some sites. How do I make adjustments? I can not see text on certain webpages. What command changes the color or texture of the fonts or texts

As of 4/20/ 2026 When attempting to save pictures or saved pictures, Fire Fox is only offering Full view , and showing full view as the only option regardless of the formats, and especially the center option which I use with my desktop black background. This is one of my favorite features of Firefox and looks like a glitch. I would suspect Windows , except that Firefox shows the formats of center, stretch, tile, and each one shows only the full view in the display box. does anyone else have this problem? I am stressed...

I gave permission to access/show my location. I live in Western New York. When I do any searches instead of showing results in the Buffalo-Niagara Falls area of New York, I get search results from Canada. How do I turn off or correct my location?

Been having tab crashes every couple of minutes - doesn't matter what the site is, the tab will crash out and I'll have to refresh. I have a laptop that is synced that I also use that doesn't have this issues - it's isolated to the PC.

Tried sfc, DISM, hardware and memory checks - all come back good. I'm inclined to believe it could be something on the operating system and not hardware, but I also recently reinstalled Windows. I had another thought that it could be something with JavaScript (seemed like a common theme in the error reports, but I'm not 100% what I'm looking at or for).

ein nettes Hallo,

seit einiger Zeit habe ich Probleme das Firefox die Verbindung zum Internet verliert. Andere Browser wie zum Beispiel Google haben diese Probleme nicht. Ich habe Firefox neu installiert, den Cash geleert und auch schon mit dem Fehlerprogramm von euch laufen lassen, es wird nicht besser, vielleicht kennt ihr noch eine Lösung die mir helfen kann...

Beste Grüße,

Last week I downloaded the latest update for Firefox. After that I could not open websites I often use, such as etsy.com and ebay.com where I sell items. Also could not connect to Firefox Support. Yesterday, 4/19/2026 I uninstalled and reinstalled Firefox. I have box selected to open new tabs instead of new window, however, when I click on a line from my email it opens new window which causes me to have to sign-in to my accounts again, multiple times today. Also, after the latest update I cannot use my main modem network, have to use another wifi network. Also a couple of times today when I open a tab it is trying to use the primary network and pages will not load. I need help in resolving issues caused from last weeks update. I know this is very long but felt I need to tell you what is happening so you'd better understand steps to take to resolve issues. Thanks for your help.
