Tabs always start in mute mode. I can turn it on by pressing speaker logo in the tab. The problem is when I shift to a new tab, the previous tab mutes automatically. For example: I listen to YouTube music and want to check my mail. When I shift focus to the new tab the first mutes it self. Any suggestions please. Sincerely Oscar.

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Hi

When I visit the webpages of the Swiss Federal Post Service

    https://www.post.ch/de/kundencenter/onlinedienste

then the scroll bar will not be displayed even though the page is longer than what can be displayed on my screen. As soon as I return to another URL the scroll bar is visible again when needed.

Does anybody know what I can have a scroll bar also for this webpage?

Cheers, Pepe

Hello,

Everytime I have to close my pc with updates or if I just close/ restart it or if it crashed and I have to restart everything, all my most recent tabs (when I do restore last session) are gone but I get all the tabs back from weeks or even months ago. It's very annoying especially I do research and study. I really don't understand. It's like going back in time every time it starts again  :( What is happening ?

Thank you for your help ! Vanessa

Yea I don't need help but I cannot believe you guys made an Firefox installer so small so its only "390 KB" and a floppy disk only has 1.44 MB meaning it can fit into a storage thing from 40 years ago. Man that's crazy!

(also I'm using your Firefox browser on my crappy 8 years old Windows 10 laptop, and ngl its great even tho it sometimes uses a lot of cpu and ram usage. It loads fast and the first time I got your browser it ran great and this old laptop finally can run videos on 720p instead of on Chrome barely running 240p)

My emails are threading up, even ones that have nothing to do with each other. I've tried 'collapsing threads' in the 'view' menu, but it doesn't seem to help. With so much threading going on, I can't even find some of the new emails that I am alerted to.

I trust this message finds you well. I am currently using Mozilla Firefox as my preferred web browser and I'm interested in ensuring that I have the latest version installed for optimal performance and security.

Could you provide a step-by-step guide on how to update Mozilla Firefox to the latest version? I'm curious about the frequency of updates and whether the process varies for different operating systems I'm using windows.

Additionally, I'd like to understand if there are any precautions I should take before initiating the update, such as saving bookmarks or ensuring compatibility with installed extensions.

Furthermore, are there any notable features or improvements in the latest version that I should be aware of? I want to make the most of the browser's capabilities and stay informed about any enhancements.

Thank you in advance for your assistance. I appreciate your expertise in guiding me through the Firefox update process.

Best regards,

During my absence my house maid created a Google account for herself on my Firefox browser, which is confusing my browsing as it is also a default account. I wish to remove my maid's account but cannot find how. Please help. I am using Windows 10.

I have search separated from the url bar, and I have Firefox Suggest configured to only use history for tab completion. I've noticed a couple problems.

• Search is being prioritized over options in my history. I have the separate search box, if I wanted to search I would use it. If I type a single character I want the most common result from my history to be the result of hitting tab.
• I've noticed recently that I'm getting sponsored results even though I have them disabled. It's somewhat inconsistent, and I've only noticed it in one of my profiles. Specifically I am used to "w <tab>" taking me to weather.gov but I'm getting sponsored results for AccuWeather. I clicked the "feedback -> not interested" button but this is concerning that Firefox is ignoring preferences and there's a pattern of sending data to Google and AccuWeather despite me configuring the browser not to.

I found an answer to this question, but I need it in English; how to do this if you're not a programmer. The new feature is beyond annoying, so if someone wants to work on making it optional, that would be a super improvement, but I'll be happy if I can just turn it off! Thank you

After a update my browser was running very slow, I'm not sure what I did but my whole browser, including history and bookmarks and add ons reverted back years. But I have a whole folder of Old Firefox Data which is from today.

How do I get this back on there and get everything back to normal?

I restarted my computer and when I booted Firefox up it looked completely different. I'm assuming they updated, but updates never impacted my settings before and in this case none of my sessions or history is left.

I logged in to my Mozilla account and that recovered my extensions, though not my toolbar settings.

The real issue is that all of my tabs and windows are gone. In History, "Recently closed windows" is greyed out and Recently closed tabs shows nothing but what's been opened since I restarted.

Is there any way to recover my history?

Edit:

Resolved: Somehow a blank profile had been set as the default.

Hello! Since updating to the last version (119.0.1), Firefox started keeping my open tabs between sessions. This is a behavior I don't want, and the only solution that I found told me to enable "clear history on close", however that is also not ideal, because I don't want to clear my history. The "Open previous windows and tabs" setting is off and my homepage is set to Firefox Default. I don't know where else to look for such a setting, except in the about:config, but even there I'm not sure which one is causing the issue. Any assistance would be appreciated.

Windows 10 Pro 21H2, Firefox 119.0.1

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

I'm using Firefox for Windows and usually have a few set pages that appear every time I open a new window. Every now and again, I have to add, remove, or change one of these pages. The issue is that I have to see something like this whenever I want to change anything.

`https://link1.url.com/|https://link2.url.com/|https://link3.url.com/|https://link4.url.com/|https://link5.url.com/`

Naturally, whenever I open a new window in Firefox, this is automatically interpreted to open multiple pages. However, this way of displaying them is still inconvenient. I want to know if we can get something more like this.

https://link1.url.com/ https://link2.url.com/ https://link3.url.com/ https://link4.url.com/ https://link5.url.com/

Is there a way to edit the Settings UI to see a multi-line list with the ability to add, remove, or change these links individually? Thank you.

Some websites, like my bank, don’t let you paste into the password field. I don’t want to manually type in the password. I found a workaround:

1. Go to about:config
2. Search for dom.event.clipboardevents.enabled
3. Double-click it to change the value to "false"

But the problem is that pasting into a google document no longer works. I have to revert the value back to “true” to get copy-pasting working in a google document.

Is there a way to have the best of both worlds: paste in google docs and paste in sites that block pasting, like my bank?
