Please let us know if this solved your issue or if need further assistance.

Thank you for your reply. Unfortunately, having done everything you suggested didn't solve the problem. Both add-ons I mentioned continue to not retain their tab-reloading settings.

I'd greatly appreciate any further suggestions.

Thanks, Jordan

Make sure you do not run Firefox in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).

• https://support.mozilla.org/en-US/kb/private-browsing-use-firefox-without-history

• Options/Preferences -> Privacy & Security
  Firefox will: "Use custom settings for history"
• remove checkmark: [ ] "Always use Private Browsing mode"

In case you use "Clear history when Firefox closes" or otherwise clear history.

• do not clear the Site Preferences

• Options/Preferences -> Privacy & Security
  Firefox will: "Use custom settings for history":
  [X] "Clear history when Firefox closes" -> Settings
• https://support.mozilla.org/en-US/kb/delete-browsing-search-download-history-firefox

• clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exception for password and other website specific data
• clearing "Cookies" will remove all selected cookies including cookies with an "Allow" exception you may want to keep

Thank you cor-el! But I don't use this mode and do not clear the browser.

Anybody with experience with the two add-ons I'm trying to use? Is it possible both of them fail such basic function as retaining the user settings? Hard to believe, no?

Thank you again!

try to use just one,

if all of them doing the same thing.

Thank you, FFus3r.

I have always used/installed only one tab reloading add-on at a given time...

Right now, I'm using ReloadMatic, here:

https://addons.mozilla.org/en-US/firefox/addon/reloadmatic/

The problem I reported is that both this one and the other, Tab Reloader, do not retain their settings, surely not after the PC is turned off and then on again and, I suspect, sometimes even when it stays on.

Thank you again, Jordan

see this page:

• https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save

if it didn't help then read About this extension you mentioned:

In contrast to ReloadEvery, ReloadMatic will stop reloading a tab when its URL changes. If you want the old behavior back, enable the Sticky Reload option. You can make it turned on by default in the addon settings.

Thank you, FFus3r.

First the easy part, ReloadMatic: I'm already using the Sticky Reload setting, and I am not changing the url of those tabs I want to reload. However, when I restart the PC, tab reloading gets reset to "don't reload."

Now, if you look at at the first advice I got (above), it involved removing FF and its files and a fresh reinstall. I did that.

As best as I can tell, FF remembers everything else: the multiple tabs I have open come back after I close FF, shut down the PC and then turn it back on and restart FF. I don't believe any of my settings get 'forgotten,' other than the tab reloading add-ons -- both the ones I've tried so far, as detailed above.

Reviewing your advice, I believe I already have a "refreshed" FF, just by virtue of reinstalling it, no? (That's the first item here: https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save .) And, I'm not sure that any of the following items apply, or might they? Would you point to a specific setting or solution among the several mentioned that you believe to be appropriate?

I am concerned about changing default or custom settings that are now working as intended or desired, that's why I'm asking.

Thank you again, Jordan

try this first:

• https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save#w_user-js-file-overriding-firefox-settings

because it says:

certain settings change back each time you start Firefox.

Hi Jordan, is the problem mainly or only with tabs restored from a previous session?

At the point of session restore, tabs other than the active tab are in a "pending" state, and when a restored tab is viewed, it loads a cached version. Possibly this disables any code the add-on had injected into the tab and you need to reload the page at least once by hand to get the add-on to start working there again.

Maybe that's not the only place you see the problem, but I could certainly understand why it could occur with restored tabs.

Thank you, FFus3r.

Unfortunately, there's no User.js file in my FF profile. And, again, I believe all other settings (open tabs, homepage, etc.) are retained between sessions.

UPDATE: I also confirmed that the prefs.js file isn't locked and I removed a couple of prefs-n.js files. No change.

Thank you, jscher2000.

If I understand your question correctly, I believe the problem is only experienced after I restarted FF. It seems to me that the reload settings remain in effect for as long as I don't close FF. But I will retest this (with ReloadMatic) just to be sure.

As to the cached version of the (inactive) tabs interfering with the add-on's instructions, I will test that as well. I am inclined to doubt it: When I discover that the tab is no longer reloading, I reload it manually (CTRL+F5); doing so reloads the tab but does not restore the prior reloading instructions -- at least not on the drop-menu of the tab, where the reload settings are visible. With Tab Reloader, the other add-on I tried, it is very easy to detect that the settings are gone: there's an icon that indicates how many tabs are set to reload, and it grays out when the settings are lost. There's no change of status after I manually reload a tab. Therefore, I think those reload settings are truly gone.

So, it is still a puzzlement, especially given that this is a new install of FF -- yes, I know that the profile is the same old profile...

I would greatly appreciate your suggestions.

Thank you again, both! Jordan

It appears like I fixed the problem...

The following plugin: Don't touch my tabs! (rel=noopener), which I had in place for a long time, was conflicting with Tab Reloader. Once I disabled it, Tab Reloader started to retain its settings. I'm hoping it stays just like this...

Thank you all for your help -- much appreciated! Jordan

Regrettably, this is a clear case of premature sense of success.

Although a few short-term turning-off and restarting of FF resulted in the Tab-Reloader retaining its settings, subsequent repetitions of the same resulted in lost settings.

Any thoughts?

Many Thanks, Jordan
