For those of you whose problem is with SmarterMail, my e-mail provider thinks they have a solution, although it has not yet been implemented.

I quote from Hostgator tech support: "I have found a Smartermail update that was released on 7/24/14 that fixed this issue (http://www.smartertools.com/smartermail/releasenotes/v11.aspx - Version 11.7.5318 (2014-07-24))."

The patch won't be loaded to their servers until at least tonight. I'll post again if it is successful.

I suspect that this is a workaround on Plesk's part (developer of SmarterMail) for a Firefox bug, but I'll take anything that fixes the webmail system.

Many site issues can be caused by corrupt cookies or cache.

• Clear the Cache

Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

and

• Remove Cookies

Warning ! ! This will log you out of all sites you're logged in to. Press the Alt or F10 key to bring up the tool bar. Followed by;

Windows; Tools > Options Linux; Edit > Preferences Mac; application name > Preferences

Then Privacy. Under History, select Firefox will Use Custom Settings. There is a button on the right side called Show Cookies.

If there is still a problem, Start Firefox in Safe Mode {web link} While you are in safe mode; Press the Alt or F10 key to bring up the tool bar. Followed by;

Windows; Tools > Options Linux; Edit > Preferences Mac; application name > Preferences

Then Advanced > General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.

Hi JBFixit, thank you for reporting this in multiple threads. In order to make sure you get any updated script files the next time you try your SmarterMail, please do clear your Firefox cache before logging in.

As a temporary workaround, you can block website scripts from resizing windows. It's a bit of a sledgehammer, but another user who has this problem indicated that it does stop the SmarterMail script from rolling up the window.

Here's how:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste dom and pause while the list is filtered

(3) Double-click the dom.disable_window_move_resize preference to switch it from false to true.

Problem solved. Hostgator's administrators applied the 7/24 patch to SmarterMail

http://www.smartertools.com/smartermail/releasenotes/v11.aspx - Version 11.7.5318 (2014-07-24)

on Saturday night 8/2 and that solves the problem for me. I'll be turning my people's Firefox updates back on.

Thank you, jscher2000, for the above workaround.

SmarterMail's a commercial product used by both in-house mail servers and e-mail hosting providers, so there may well be others in need of both the patch and your workaround.
