Refresh Firefox - reset add-ons and settings

This feature is available on Firefox for desktop or laptop computers.

This feature has been improved in the latest version of Firefox. Update Firefox to the latest version to use the improved version.

If you're having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its default state while saving your essential information like bookmarks, passwords, and open tabs.
Note: Extensions and extension data are removed.

Refresh Firefox

  1. Click the menu button New Fx Menu and then click help Help-29 .
  2. From the Help menu choose Troubleshooting Information.
    If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
  3. Click the Refresh Firefox button in the upper-right corner of the Troubleshooting Information page.
    Refresh 35 Win Refresh 35 Mac Refresh 35 Lin
  4. To continue, click Refresh Firefox in the confirmation window that opens.
  5. Firefox will close to refresh itself. When finished, a window will list your imported information. Click Finish and Firefox will open.
Note: There's also a Refresh Firefox button in the Firefox Safe Mode window, if you can't start Firefox normally. If you are unable to find the Refresh Firefox button on your version of Firefox, you can also do a manual refresh by creating a new profile. See instructions on how to create a new profile.

What does the refresh feature do?

All of your Firefox settings and personal information are stored in a profile folder. The refresh feature works by creating a new profile folder for you while saving your important data.

Add-ons which are normally stored inside the Firefox profile folder, such as extensions and themes, will be removed. Add-ons stored in other locations, such as plugins, will not be removed but any modified preferences (such as plugins you have disabled) will be reset.

Firefox will save these items:

  • Bookmarks
  • Browsing and download history
  • Passwords
  • Open windows, tab groups and tabs
  • Cookies
  • Web form auto-fill information
  • Personal dictionary

These items and settings will be removed:

Note: Your old Firefox profile will be placed on your desktop in a folder named "Old Firefox Data". If the resetrefresh didn't fix your problem you can restore some of the information not saved by copying files to the new profile that was created. If you don't need this folder any longer, you should delete it as it contains sensitive information.

This article, like all Firefox support, is brought to you mostly by volunteers, who keep Mozilla proudly independent and open source. Keep browsing freely!

  • Reset Firefox - this first implementation is a button in about:support. It automatically creates a new profile and migrates over your bookmarks, history, passwords and form data.
    • Rename Refresh Firefox - reset add-ons and settings to "Reset Firefox – easily fix most Firefox problems" - new version of the article documents this feature. Note: this article was originally created as temporary solution while this feature was being worked on.
    • Create a template or templates that mention that this feature can be used instead of troubleshooting steps <snip>

A few days ago my Sony VAIO updated the flash player to 11.3.0 since then, a very strange noise heard whenever playing videos on youtube.

Scanned for anti-virus: and the system was clear Re-installed the sound card drivers to tackle the problem, no outcome.

After troubleshooting the problem, it appeared to be that the new flash player plugin which adobe has released very lately; is the trouble maker. after downgraded the flash player to 10.3 everything was spot on.

Here is the solution: 1. Uninstall the 11.3V using this file from adobe: http://download.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe

Install the 10.3 V. from Adobe: http://fpdownload.macromedia.com/get/flashplayer/current/licensing/win/install_flash_player_10_plugi...

Hope this will end your misery as it did to me!

Cheers.

The Troubleshooting Information page may be missing the "Reset Firefox" option in some cases (e.g., when using a non-default profile) and the-edmeister asked whether this should be added to the article. See this thread for more information:

This is an edge case and I don't think we need this in the article as it will just add complexity for no real benefit. That's the only instance of the problem I can find on the forum. In that case the user is using an unsupported version of Firefox.

Thanks. Michael.

I posted a reply to Ed in the KB article forum thread he started, here:

The tracking bug for the Reset Firefox feature is Bug 851364 - (reset-firefox) [meta] Reset Firefox to its default state

(For the record) Personal dictionary is saved in Fx23 The related bug is Bug 834034 - Migrate persdict.dat when resetting Firefox

Fixed in Firefox 25 (added to "Need changes") Bug 833943 - Migrate open windows and tabs when resetting Firefox

I don't have a menu bar so I can't access reset.

This forum is for improving the Knowledge Base article, which is written for different operating systems. Do you see a version selector at the top of the article? You can change that:

For Windows 7/Vista (which uses the Firefox button by default):

At the top of the Firefox window, click the Firefox button, go over to the Help sub-menu and select Troubleshooting Information

For Windows XP (which uses the menu bar by default):

At the top of the Firefox window, click the Help menu and select Troubleshooting Information

You can then click the Reset Firefox… button in the upper-right corner of the Troubleshooting Information page.

After resetting Firefox, it now stops me from automatically opening a new page. The message comes up "Firefox prevented the page from automatically re-directing to another page ". Annoying and time consuming. How can I get back to normal ? Thanks,

Hi Adobe Photoshop CS6 Photoshop before installing firefox was working fine but after installing firefox does not work as you can see in the picture. Adobe Flash Player update but the error continues.

The image "There are errors after installing photoshop." does not exist.

This How to article, "Reset Firefox – easily fix most problems" https://support.mozilla.org/kb/reset-firefox-easily-fix-most-problems/

.... redirects (not sure how) to "Reset Firefox -- easily fix most problems" https://support.mozilla.org/kb/reset-firefox-easy-fix-most-problems which is in the Administration category and its History is: May 13, 2014 12:31:46 AM Current MT jsavage test article only - no linux or sub 23 versions

The Administration category has three different "Reset Firefox" articles:

I also asked about this in the KB articles forum:

/forums/knowledge-base-articles/710522 [Attn: Admin] What's going on with the "Reset Firefox – easily fix most problems" article?

Joni said August 1, 2014 6:19:47 PM EDT Modified by Joni on August 1, 2014 6:27:27 PM EDT

Yikes, thanks for catching this, Alice. I don't know why this redirect is happening, but I'll find out what's going on.

Background: we created three other versions of the "Reset..." article in the Admin category for a multivariate test. We wanted to see if the helpfulness rating changes significantly if we stop documenting anything older than Firefox version 23 or if we use only Windows and Mac screenshots. The results show that the ratings don't change.

Edit (3:25 PM PDT): I thought the problem might be caused by duplicate titles so I changed the title of the test article. That still didn't fix it. I'll get on top of this.

Related bug, filed by Joni:

  • Bug 1047693 - "Reset..." article keeps redirecting to test articles

I talked to Kadir about this. The test is still running, which might be the reason for the redirect. Kadir will file a bug to stop the test. As soon as Ricky removes the code, we'll see if things get back to normal.

Starting in Firefox 32 when you reset Firefox, there's an additional Import Wizard step. I tested this in Firefox 32 Beta on Windows 7 and here's a screenshot: https://support.mozilla.org/en-US/gallery/image/18491 Fx32Reset-ImportWiz When I tested the reset feature in Firefox 31, the Import Wizard does NOT appear*. Related bug:

  • Bug 1036186 - Reset Migration wizard no longer skips the first step to choose a browser

Unless this bug is fixed before Firefox 32 is released and the new "Import Wizard step is eliminated, we should probably definitely mention it in this article. (The correct action is to keep the default Import Wizard option, to import data from Firefox.)

Note: This article is currently redirecting to a "Test" article. I'm not sure which article will need to be edited, this one or the test article it redirects to. Related discussion: /kb/reset-firefox-easily-fix-most-pro.../5398 Why does this article redirect to an Administration test article created May 13?


[*] However, with a Firefox 31 reset you I see a "Well, this is embarrassing ...." window shown here (a bug? ) that you I don't see in Firefox 32 Beta.

Will the test be completed before Firefox 32 is released? If it isn't and a new revision is needed, which article should be edited?

See /kb/reset-firefox-easily-fix-most-pro.../5417 [Fx32] Import Wizard reset step (bug 1036186)

P.S. The following is copied from this "Investigation" bug:

  • Bug 1032958 - Investigation: Reset Migration wizard no longer skips the first step to choose a browser

 Verdi [:verdi] 2014-07-01 11:45:23 PDT
Created attachment 8448886 [details]
import-dialog.png
In Firefox 32 we added a screen where the user can choose what to import (data from another browser, data from Firefox, or nothing/cancel). In previous versions, we don't provide this choice and just automatically import the Firefox data because that's how the feature was designed.
This new option causes a couple of problems:
1. This screen requires action on the user's part.
2. This screen has multiple (4-6) options with only 1 right choice (Firefox - the default). This invites the possibility of the user breaking the reset process and ending up with a blank profile which is explicitly not the purpose of the reset feature.
Video example of the difference: http://people.mozilla.org/~mverdi/video/reset-change.webm
We should remove this screen from the reset flow.

Ricky fixed it today, in the bug that Kadir filed:

P.S. Things are now back to normal (no more redirect).

For the record, here's the bug:

  • Bug 1035557 - about:sessionrestore shows instead of about:welcomeback after a reset

Thanks, Alice.

I've added the import step in the template for this article. I'll check 32 again when it gets closer to release and remove the step if applicable.

Oh, and the template I'm referring to is Template:resetsteps.

I didn't realize that the edit needed was in Template:resetsteps , not this article. Thanks, Joni.

I made an edit to the template to change {for fx29} to {for =fx29,=fx30,=fx31} since you had both {for fx 29} and {for fx32} sections, which caused a duplication.

See bug 1036186 comment 34 dated 2014-08-21 13:34:24 PDT. The fix for this bug has been approved for Firefox 32 beta (it waspreviously approved for 33 aurora).

The recent changes made in Template:resetsteps can be reverted.

bold text I get a Firefox unresponsive message and freezes all open tabs even Chrome and the second problem...scripts running, stop or continue and neither works . I uninstalled and reinstalled firefox and no difference...HELP

On the about:support page it seems the reset button does not appear if your using a profile that is not the default.

Soooo maybe there should be a note for those users? Or maybe we dont write things like that for advance users in the articles?

I was just trying out the article so i noticed.

This came up when the Reset Firefox feature first came out. It's an "edge" case that doesn't need to be documented. Related discussion and links to previous discussion threads is here:

It seems "Reset" feature is going to be renamed to "Refresh" in Firefox 35.

Yes, this is on the Need Changes list for "Template:resetsteps". I'll add this article to that list also, since its content (and title?) will also need updating, to include "Refresh" for Firefox 35.

From the Template:resetsteps discussion thread, /en-US/kb/templateresetsteps/discuss/5549 [Fx 35?] "Reset" will become "Refresh"


Related bugs:

  • Bug 1027884 - We need a more appropriate name for "Reset Firefox"
  • Bug 1063702 - Update all Reset Firefox strings and relevant UI to reflect improved copy

As far as updating this article goes, I made a new revision with the comment, Reset -> Refresh in FX35. DO NOT APPROVE until "Template:resetsteps" is updated for fx35!

P.S. A revision to "Template:resetsteps" is pending review/approval. See /en-US/kb/templateresetsteps/history.

The current title is "Reset Firefox – easily fix most problems". Since "Reset" will become "Refresh" in Firefox 35, the obvious choice would be: Refresh Firefox – easily fix most problems

Alternatively, we could rename this article to something that would apply to all Firefox versions by not using "Refresh" or "Reset" ... maybe: Restore Firefox to its default state Automatically repair Firefox  ? Use the automatic repair tool to fix Firefox problems  ?

"Restore Firefox to its default state" is probably too "scary" and no longer describes the feature which deletes less and less in future versions. See Bug 1027884 - We need a more appropriate name for "Reset Firefox"


Verdi [:verdi] 2014-06-19 15:14:33 PDT
The word "reset" was chosen when we first launched this feature and it did indeed reset and delete many things. Over time we've kept the repair ability of the feature while saving more and more of your critical information. We want to make this option discoverable for users and now need a name that is less scary, more appropriate and helps users choose the right time to use it.
<snip>
For reference IE, Chrome and Safari all call it reset but their versions are somewhat more destructive. 
<snip>
We also plan to have it deactivate and save your add-ons and their data instead of deleting them (Bug 1017919). 
Verdi [:verdi] 2014-08-06 13:03:41 PDT
Thanks Matej! Refresh has grown on me. I also like Repair. 

I'd still like something without "easily fix most problems" in the title. People get angry when they use the feature and it doesn't fix their problems, and they end up with no extensions, Applications settings (mimeTypes.rdf) and preferences (prefs.js) are reset to defaults, etc. The process is easy but it may not fix MOST problems.

Here's the "What links here" list for this article. <snip> we may want to go back and update the links in the above articles with the new title, <snip>

Update: I'll edit those articles (except for the redirect and archived articles) to change the links to the renamed article.

I have a concern with including "Refresh" in the title. Out of context, "refresh" could be interpreted as "reload" (as in reloading web pages).

It's okay to use the term in the actual article body, but I'd hesitate to use in a title. Perhaps this can be solved if we add more context in the search summary.

I don't have a solution yet, but I think one of your proposals ("repair") could work. I'll do more keyword research and post back soon. Also, I agree with you on removing "...fix most problems".

Thanks Joni.

This article is still pending review for Firefox 35 changes. I see you reverted made a number of edits to my last change to /kb/templateresetsteps - WHY ?!The template no longer works now.

/kb/templateresetsteps/compare?locale=en-US&to=85733&from=8...

In your last revision, /kb/templateresetsteps/revision/85733 nothing shows for fx35 except the Refresh button.

For fx34, it says "Click the Refresh button in the upper-right corner of the Troubleshooting Information page".

Ah, I see why you did that: https://support.mozilla.org/forums/knowledge-base-articles/710972

I still made a new revision to change {button Refresh} to {button Reset} for fx34

Sorry, Alice! I was really slow in posting this explanation: https://support.mozilla.org/en-US/kb/templateresetsteps/discuss/5823

Thanks for fixing fx34 in the article.

There's a new "Refresh Firefox" button that you can add to kb articles using the code, [[Button:refresh]] , which will directly start a Firefox reset. Joni just added it to "Template:resetsteps" for fx35, as shown here: /kb/templateresetsteps#firefox:win7:fx35

Related discussion: /forums/knowledge-base-articles/710972 Refresh button

Related bug: Bug 1087865 - Add the ability to include a Refresh Firefox button in a support article.

I looked at search data for "reset", "restore", "repair", "refresh" and "fix". Reset is still the most overwhelmingly popular search term, followed by restore. Refresh, as I thought, has more to do with searches like "where is the refresh button?"

With that said, I think we should still use “Refresh Firefox” in the title to help promote and rebrand the “Reset” feature. As Alice noted, "reset" isn't really accurate anyway. Here are some title suggestions:

  • Refresh Firefox - reset add-ons and settings (my top choice because it still attracts “reset” searches while promoting the new name)
  • Reset add-ons and settings in Firefox
  • Firefox repair - fix problems caused by add-ons and settings
  • Repair Firefox - reset add-ons and settings

We should also write a more descriptive search summary: “The Refresh feature repairs Firefox by resetting problematic add-ons and extensions without removing your bookmarks, passwords and other essential information."

For users on older versions, we should put a conditional note saying that Firefox has a new, improved feature called “Refresh Firefox” and encourage them to update.

What does everyone think? Any issues I'm not seeing?

I also like Refresh Firefox - reset add-ons and settings

Let's change it when fx 35 gets to general release. I'm traveling that week, but I plan to make these changes when I get back online on the 19th (if nobody has made them by then).

I noticed this revision was approved today, but nothing has been changed in this article and the title is still the same, "Reset Firefox – easily fix most problems"

In any case, its time to rename this article but there's no big rush. We can wait for Joni.

It may also be worth adding "tune up" as a keyword beause that is the description used on /products/firefox

John99 said

Yes, we can add keywords or else update the search summary to add "tune up" and "repair".

Refresh Firefox - reset add-ons and settings is Joni's suggestion for renaming this article. The current summary is:

Fix problems like slowness, crashing, unwanted toolbars, search hijacking and more by restoring Firefox to default settings while saving your important data. 

We can change the summary to something like this:

Repair or tune up Firefox by restoring it to default settings while saving essential data. This can fix slowness, crashing, search hijacking and other problems.

Done!

The new search summary looks great. Thanks for writing it.

I've renamed the article now. I'll see if we get any user complaints or confusion.

Thanks, Joni. Welcome back!
