Diễn đàn hỗ trợ Firefox

I am on a brand-new machine and having trouble setting up the Firefox browser.

When I click on a link it opens in a new window with all the tabs ready opened.

How do I open a tab without opening a new window?

Also, how do I set Yahoo.com as my default search engine?

Thank you for sharing your wisdom

In previous versions of FFx, toggling to Reader view used the same font I'd chosen in Settings / wherever. Now it's something else, in boldface with no distinctions made in original view (italics, not italics, etc). & there doesn't seem to be any way I can control fonts in Reader.

Any suggestions? In plain English, please, I am NOT a programmer or computer professional, just a regular human trying to use this new version that seems to have broken everything I liked about FFx.

When I close firefox while it's in full screen, turn off my laptop, and then open it again the day after, it opens in the small screen for some reason. I tried going to the root directory in the about:profiles section of the more troubleshooting information section and renaming xulstore.json to xulstore.json.old, and each time it worked for a few days and then it just installed a new xulstore.json and went back to opening in the small screen. This is really annoying and I don't want to switch it manually every time.

I frequently attempt to open news articles or other pages requiring form fill-in but instead get a page that advises me to disable an adblocker. I have no idea what Firefox (yes, up-to-date) uses or how I could set it to allow pop-ups for a particular site. Help!

Got up this morning and FF said all my tabs were crashed - GAH! Could not open ANY new tabs, not even a blank tab, without getting this message. Clicking on restore tabs did nothing. Closing & opening FF did nothing. Cleared startup cache & uninstalled ublock origin (the only extension I had) but that did nothing. Refresh firefox did nothing (except lose some of my preferences). Went to about:crashes and all it says is "No crash reports have been submitted." Every other suggestion I found online was beyond my comprehension. FF DOES work in troubleshooting mode only, but I lose some important functions in that mode. I've been using FF almost since it was born and have NEVER encountered a problem like this before. I hope someone can help!

After signing into an account with Schwab.com, the site has a "Launch" button that opens the Schwab "Streetsmart Edge" trading platform. However, after signing into Schwab.com with the Firefox browser, clicking on the "Streetsmart Edge" Launch button does not work. "Streetsmart Edge" does not open.

This problem only occurs when using Firefox. If using Microsoft's browser there is no problem.

Previously, until about two month ago, the Firefox browser never caused this problem. It worked fine for many years.

I prefer the Firefox browser versus Microsoft. Please research and repair this issue.

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

I already found many users asking the same, but they didn't get a reply.... at least I didn't see any.

I want to protect my password memory with a master password - fine. But in 99% of my time, I don't need to enter login data. Even worse, if FF starts on an "invisible" monitor, I cannot move the window.

Is there a way to have FF prompt only for the password if I attempt to log into a site ? ... it already does that when I cancel the start-up prompt.... so is there an "auto cancel at startup ?"

I've got an M2 MacAir running the latest version of Sonoma. Within the last week, the battery power has fallen off a cliff. It barely runs for a couple of hours and recharging takes nearly half a day. I'm not running anything unusual just social media & YT videos. This seems to have coincided with the latest Firefox update. I was wondering if this might be contributing to it or if this is a common problem since Sonoma & FF updates?

Anyone any ideas?

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

I saw through several threads on how to try and fix this issue but none seem to work for me, when im trying to watch a video on regular firefox it doesnt work but on safe/troubleshooting mode. and it works when i put the video in a new tab but not on the main site. and while looking in the console i get this "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://static1.e621.net/data/ab/71/ab71a84c62b9d77fa0eb68c5e64dc165.webm. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 206. any help will definitely be nice

open app on desktop, closes within 40 seconds whether browsing, playing a bookmarked game or just watching opening page. I uninstalled app, reinstalled with saving bookmarks then without saving apps, it stills closes

I keep getting this message every time I try to access a website I haven't accessed for a while : see attached graphic.

How can I get this to stop ?
