Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Problem still there.

Some Firefox 74 users are having problems with websites that require certain types of local storage such as Gmail and Twitter.

The sites won't load in regular windows, but will load in private windows because private windows use memory-based storage and don't need to access the disk-based storage files used in regular windows.

These users also have failures on the second through fourth tests on this page:

https://firefox-storage-test.glitch.me/

If that matches the problem you're having:

Past advice related to that diagnostic result was as follows:

(1) Next Gen Storage Setting

This setting is normally false (off) but in case it somehow got turned on, see the steps in the following article: Some pages or page elements fail to load after updating to Firefox 70.

If that doesn't fix it (after a restart, perhaps):

(2) Flush Data for Problem Site(s)

If you tell Firefox to remove all data for a site, that should include removing its storage folder, as well as its cookies, history, and customized permissions. If you don't want to remove all data, you might be able to fix it temporarily by just removing the "cookies and site data". Here are how to access these options:

(A) Cookies and Site Data

Open the Options/Preferences page using either:

• Windows: "3-bar" menu button (or Tools menu) > Options
• Mac: "3-bar" menu button (or Firefox menu) > Preferences
• Linux: "3-bar" menu button (or Edit menu) > Preferences
• Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the left column, click Privacy & Security

On the right side, scroll down to the Cookies and Site Data section

Click the Manage Data... button to open the "Manage Cookies and Site Data" dialog.

In the dialog's search box, type goog to filter the list. Select the domain(s) relevant to Gmail and click the Remove Selected button. Then click the Save Changes button at the lower right.

Any difference when you try the site again?

(B) Forget About This Site

• Open the Library window using Show all History (Ctrl+Shift+h)
• In the small search box at upper right, enter enough to uniquely identify the site, such as mail.goo -- we want to avoid accidental misclicks with this feature
• Right-click a matching history entry and choose Forget About This Site

Because Firefox modifies a number of files, this may take some time to run.

Any difference?

If that doesn't fix the problem site(s):

(3) Have Firefox Generate New Storage Folders

This will cause loss of some data saved locally by websites and add-ons.

Open your current Firefox settings (AKA Firefox profile) folder using either

• "3-bar" menu button > "?" Help > Troubleshooting Information
• (menu bar) Help > Troubleshooting Information
• type or paste about:support in the address bar and press Enter

In the first table on the page, on the Profile Folder row, click the "Open Folder" button. This should launch a new window listing various files and folders in Windows/File Explorer.

Leaving that window open, switch back to Firefox and Exit, either:

• "3-bar" menu button > Exit
• (menu bar) File > Exit

Pause briefly while Firefox finishes its cleanup, then right-click the storage folder and Rename to something like storageOLD -- the purpose of renaming instead of deleting is the possibility of reinstating the old folder or mining it for essential data.

Start Firefox back up again. Do sites work again?

Problem resolved.

Point (2) (A) above worked.

Thanks

Step 2(A) worked for me, too.

BUT, I have to do this step virtually every day to access Gmail on my Windows 10 PC. Stored bookmarks and pinned tabs in Firefox just don't work after some period of time; perhaps it is PC "Sleep" mode overnight that triggers this behavior change.

Mozilla/Firefox really should come up with a fix to this repeating problem!

Thanks in advance!

My problem is a little different. I updated to the latest Firefox 74 & couldn't get anything but a blank white page when I click Firefox to get online. I've tried several different solutions/fixes, but nothing worked. I have to literally restore my computer to an earlier time, then download an older version (72) of Firefox & it works like a charm. But, now, every time I get online, Firefox is asking me if I want to update! At this point, no I don't because I've tried the update 3 different times & it just does not work! I've used Firefox for over 10 yrs. & never had this problem before. I don't know what to do & I can't seem to find any help anywhere! Help!

FireSpirit Follow the instructions below and include what you have tried.

Describe the problem in brief (one line). Then press <enter>. The website will display any prior posts that might help you. If nothing on the list can help, at the bottom press the button; None Of These Solve My Problem.

Now enter all the relative information on the problem. At the bottom of this, you can Add Images.

I ran through the solutions suggested above (Firefox 76.0.1 64-bit). It appears my problem was NoScript (11.0.26). When I set NoScript to Temporarily Trusted, to allow Google to run scrips, Gmail loads.

I don't believe I would have changed this setting lately, but that's certainly possible. So whether I did, or whether something in a recent update to either Firefox of Gmail means I need to allow it to run scrips, is unclear

I'm one of those people who believe Google products are borderline spyware, so I'm reluctant to set this to Trusted to Allow Scripts Permanently. I'll see how this plays out. Now that I know what to do, it's a minor annoyance but not that much of a problem to set NoScript to Temporarily Trusted each time I load Gmail.

Don

Hi Don, NoScript is an add-on for those who prefer to browse in paranoid mode; it's not something that normally just shows up out of the blue on its own. You may want to review your extensions. I'll put steps for that at the end.

You won't have a good experience using Gmail on the web without JavaScript enabled for several Google servers. You could consider using a separate mail reader to work with Gmail instead of the browser. Or you could set your Gmail account to forward a copy of all your incoming messages to another mail provider you trust more and use that as your main email site.

You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons
• type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions.

Then cast a critical eye over the list on the right side. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything you do not remember installing or why? If in doubt, disable (or remove) -- don't let strangers linger in your Firefox.
