Diễn đàn hỗ trợ Firefox

So for the last little while, Facebook has been making a complete nuisance of itself on firefox. This isn't a browser problem, because the other tabs I have open work perfectly fine, but FB takes forever to load, and any button I press to interact with it, (like the reload button,) also lags, (but, again, works fine on other tabs,). It doesn't even register links as being clickable for a good minute after loading. The page also seems to reset every time I switch from another tab to it, showing a blank page with a loading symbol. I have tried deleting the entire history, and restarting the browser, and deactivating the adblocker, (the only extension active) and nothing seems to help. Does anybody know why it's doing this, (other than because the company follows the 'if it isn't broke, break it' theory, which we all already knew,) and how to fix it?

Since a couple of months I see only [object Object] instead of code blocks on (almost) all web pages. For example on StackOverflow.

Any ideas what could cause this?

With the latest update to Firefox (116.0.1) typing anything in the search bar looks as though my keyboard is mapped to everything - every keypress does something different. This only affects Firefox, no other program behaves this way (Word, Excel, Discord, etc.).

Currently running Windows 10, AMD Ryzen 7 1800, DDR4 RAM, Malwarebytes, and ZoneAlarm Extreme Security version: 15.8.139.18543. Had to revert back to Firefox 113 to type this via downloading it via Edge.

I use Pinterest quite a bit and somehow a great deal of pins have disappeared.

This happened once before when I was using Chrome, and I was able to go digging into my cached files and find the cached versions of the thumbnails of my Pins, so I could somewhat recreate them based on that.

I'm not sure how to go about that with Firefox. Would any information (specifically images) be stored from a previous version of a webpage?

Thank you!

How do I permanently remove this new Bing search engine from Firefox Browser? I don't like Bing. I go into settings, and change my default search engine to Google. But, the moment I search for something it shows that its Bing in the top left corner of the page. I can't get rid of it. Please help! I really don't like Bing! It has never fully helped me find what I'm looking for, or been thorough when searching for what something means. Can you please help me remove Bing from Firefox Browser? I sent 2 images showing what I mean. The first shows me wanting to use google to search for a word. And, in the second is what happens after I do that. You can clearly see Microsoft Bing in the top left corner. Thank You for any and all of your help & time!

I have always read downloaded .pdf files in Acrobat. I inadvertently changed the setting to "Open in Firefox" (I got a prompt and clicked it without intending to). I have changed the preference back to "Use Adobe Acrobat" in Settings/General/Applications, but Firefox keeps opening pdfs in a browser window. How do I get Firefox to abide by my preference setting?

I just upgraded firefox to v 113 64 bit with windows 7 ultimate. Now when I watch youtube in fullscreen there's a border around the screen. i don't use picture in picture and it isn't on yet the border won't go away no matter what I do. Please fix this or i will use another browser. i will include a screenshot from youtube in fullscreen mode look at it.

I'm on the ESR and just updated from 112.0.2 to 113.0.1. I had text rather than icons displayed on my toolbar. Now the text has vanished and I can't find a way to get text OR icons back. I have a disabled extension Classic Theme Restorer installed, but I thought it was already disabled long ago. In the Customize Toolbar dialog, the unused icons are displayed with text labels. When I drag one to the toolbar, it turns invisible like all the rest.

Just recently, in the past day or so, when I do a search in the search box, all the results get redirected to Bing instead of Google, that I have in my settings as default. I have checked my settings, I even removed Bing from the list, and I still only get Bing results. Even when I go to Google and use their search box on their domain, I get Bing results. I did a virus scan without finding any problems. I'm stumped and don't understand why this happened and nothing I do can detect uncovers why this is happening.

Really irritating when I have to spend my time fixing stuff that is lurking in cyberspace!

Hi,

I recently added ESET Password Manager as an extension but I was unable to log on and use it on my laptop. In a nutshell, to be able to log on and use the extension, I needed to install the app on my phone as well and sync between laptop and phone did the rest. This solved the login issue however, there is no icon on the toolbar for the extension and if I want to use the Password Manager, I have to do it on my phone.

Any ideas on how this could be solved? I have reinstalled the extension numerous times, tried troubleshooting mode as well but that is not useful with add-ons..

Thanks S

Accidentally clicked on the Add-ons widget on the right side of the menu bar and now "add-ons manager" web page opens every time I open Firefox.

How do I stop that page from loading?

When I open the Google "Choose an account" page, my account name doesn't show up above my email address. The problem ceases only temporarily when I clear the cache and the Google cookies. Any suggestions?

After updating from version 112 to 113 - performance has dropped dramatically.

In the beginning the performance after the update was faster than before. But as of tonight and today it's much worse than it was before the update.

I noticed that the browser started using more CPU than usual. Ryzen 7 5800X3D.

Cleaned cache already two times - didn't help. Tried Safe Mode - didn't help.

Had the line

.tab-close-button:not([pinned="true"]) { display: -moz-box !important; }

in my userchrome.css which put the close button on all tabs. This no longer works.

Also there is no Close Button (X) on hover for inactive tabs.

Hey there,

I have been using the arrow keys to scroll pages more and more often and was wondering if there is a way to increase / decrease the speed when holding down the arrow keys to scroll the page?

Thanks in advance. :)

Firefox is using a massive amount of ram for an unspecified task, simply defined as "GPU" is the baked-in task manager. The attached image is after a fresh reboot, with Firefox consuming about 8 GB more than it reasonably should, with only three ish tabs loaded.

Two days ago, my firefox browser started not restoring the previous sessions. I changed nothing in the configuration and I don't remember I had a crash. The option "Restore Previous Session" does not appear in the "3-bar menu > history" and it appears grayed in the History Firefox main menu.

What I've already tried or verified following the instructions of mozilla forum: 1) Settings > general > “Open previous windows and tabs” is checked as it always have been; I unchecked and and rechecked but nothing changed; 2) Settings > Privacy & Security > “remember history” is selected. Also tried to Settings > Privacy & Security > "Use custom settings for history" with "Always use Private Browsing mode" not checked. No success 3) I also deleted sessionstore-backups folder under my profile. The new created folder, even after closing some new sessions, has only the "recovery.jsonlz4" and "recovery.baklz4" files. There is no "previous.jsonlz4" inside which seems weird. 4) through about:config I checked that browser.sessionstore.resume_from_crash was true. In fact, I have Firefox in a second computer with no sessions restoring problem. I compared all browser.sessionstore.xxxx variables and the values are the same.

I still have the problem and do not know what to try next. Reset Firefox?

I installed the Firefox browser (version 113.0.2 (64-bit)) onto a new PC running Windows 11. When attempting to clean up the Firefox cache with another utility, I noticed that the amount of space recovered was much smaller than expected. When I tried to check my profile using the Troubleshooting Information page (to open the folder) I received a message that the location was not available. I double checked with Windows Explorer and this was the case. Searching for "cache2" in Explorer located the folder/directory in a different location.

The Firefox Profile Folder should be in this location, according to Firefox's Troubleshooting Information page (anonymized information in square brackets):

C:\Users\[username]\AppData\Roaming\Mozilla\Firefox\Profiles\[character string 1].[profile name]

The best I can tell, the actual Profile Folder created in Windows 11 is located here:

C:\Users\[username]\AppData\Local\Packages\Mozilla.Firefox_[character string 2]\LocalCache\Roaming\Mozilla\Firefox\Profiles\[character string 1].[profile name]

The cache folder for the profile is located here:

C:\Users\[username]\AppData\Local\Packages\Mozilla.Firefox_[character string 2]\LocalCache\Local\Mozilla\Firefox\Profiles\[character string 1].[profile name]\cache2\entries

I am not sure if this situation is unique to me, or if this is a common occurrence with Windows 11.

The use of the Packages folder may be the result of installing an application that is not fully "Windows 11-native" or it may just be the new way Windows deals with some applications. I am not sure if the data in character string 2 is consistent, or if it is a unique string created by Windows when Firefox was installed.

If I go to the Settings and clear data, the folder that is a sub-folder of Packages is cleared, so Firefox "knows" where the data is, but the Troubleshooting Information page is confused.

If this is a common occurrence, a tweak to this page in a future release would be helpful. If it is a rare occurrence, a help article may be, well, helpful.

Thanks.
